FlexibleSUSY 2.1.0 [March, 05 2018]
* Feature: Allow user to perform replacements on beta functions,
self-energies/tadpoles and vertices. The replacement rules are
specified as:
FSBetaFunctionRules = {
{g1 -> 0, g2 -> 0}, (* applied to 1L beta functions *)
{g1 -> 0, g2 -> 0}, (* applied to 2L beta functions *)
{g1 -> 0, g2 -> 0} (* applied to 3L beta functions *)
};
FSSelfEnergyRules = {
(* applied to 1L self-energies/tadpoles *)
{ (Mass|Mass2)[VZ|gZ] -> 0 }
};
(* applied to all vertices *)
FSVertexRules = { g1 -> 0, g2 -> 0 };
* Feature: Adding three new input parameters to the HSSUSY model file
which can be used to estimate the theoretical uncertainty:
- By setting EXTPAR[201] to 0 or 1, the parametrization of the
2-loop threshold correction to lambda can be switched between
yt(SM,MS-bar) and yt(MSSM,DR-bar).
- By setting EXTPAR[202] to 0 or 1, the parametrization of the
2-loop threshold correction to lambda can be switched between
DR-bar or on-shell stop mass parameters.
- A non-zero value of EXTPAR[203] is interpreted as matching scale
Q_match. EXTPAR[203] = 0 corresponds to Q_match = MSUSY.
SLHA input field | Mathematica symbol | Description
-----------------|--------------------|----------------------------
EXTPAR[201] | DeltaYt | 0 = yt(SM), 1 = yt(MSSM)
EXTPAR[202] | DeltaOS | 0 = OS stops, 1 = DR stops
EXTPAR[203] | Qmatch | matching scale
* Feature: The Mathematica script
model_files/HSSUSY/HSSUSY_uncertainty_estimate.m has been added.
The script defines the CalcHSSUSYDMh[] function, which performs an
uncertainty estimate of the predicted SM-like Higgs mass. The
three sources of uncertainty defined in [1504.05200] are taken into
account: SM uncertainty, EFT uncertainty and SUSY uncertainty. See
?CalcHSSUSYDMh for more information.
* Feature: The Mathematica script
model_files/MSSMEFTHiggs/MSSMEFTHiggs_uncertainty_estimate.m has
been added. The script defines the CalcMSSMEFTHiggsDMh[] function,
which performs an uncertainty estimate of the predicted SM-like
Higgs mass. Two sources of uncertainty defined in [1609.00371] are
taken into account: SM uncertainty and SUSY uncertainty. See
?CalcMSSMEFTHiggsDMh for more information. Note, that there is no
"EFT uncertainty" in MSSMEFTHiggs, because all 1-loop v^n/MS^n
terms are included.
* Feature: The Mathematica script
model_files/NUHMSSMNoFVHimalaya/NUHMSSMNoFVHimalaya_uncertainty_estimate.m
has been added. The script defines the
CalcNUHMSSMNoFVHimalayaDMh[] function, which performs an
uncertainty estimate of the predicted SM-like Higgs mass. The
uncertainty is estimated by: 1) varying the renormalisation scale,
2) changing the top Yukawa coupling by higher orders (if available)
and 3) changing the stong coupling by higher orders.
* Feature: Implementing 2-loop effective potential contributions to
the Higgs pole mass in the Standard Model of O((at+ab)^2 + ab*as +
atau^2). These corrections are enabled in all FlexibleEFTHiggs
models by default and can be enabled in other SM-like models by
setting the flag
UseHiggs2LoopSM = True
in the corresponding model file. At run-time these corrections
(and the O(at*as) contributions) are enabled when the following
switches are set in the SLHA input file:
Block FlexibleSUSY
4 2 # pole mass loop order
5 2 # EWSB loop order
8 1 # Higgs 2-loop corrections O(alpha_t alpha_s)
9 1 # Higgs 2-loop corrections O(alpha_b alpha_s)
10 1 # Higgs 2-loop corrections O((alpha_t + alpha_b)^2)
11 1 # Higgs 2-loop corrections O(alpha_tau^2)
or in the Mathematica interface:
FSSMOpenHandle[
fsSettings -> {
poleMassLoopOrder -> 2, (* FlexibleSUSY[4] *)
ewsbLoopOrder -> 2, (* FlexibleSUSY[5] *)
higgs2loopCorrectionAtAs -> 1, (* FlexibleSUSY[8] *)
higgs2loopCorrectionAbAs -> 1, (* FlexibleSUSY[9] *)
higgs2loopCorrectionAtAt -> 1, (* FlexibleSUSY[10] *)
higgs2loopCorrectionAtauAtau -> 1, (* FlexibleSUSY[11] *)
}, ...
];
* Feature: Implementation of the strong corrections to the 4-loop
beta functions of the strong gauge, Yukawa and quartic Higgs
couplings in the SM from [1508.00912, 1604.00853, 1508.02680].
These 4-loop beta function contributions are enabled in all
FlexibleEFTHiggs models by default and can be enabled in other
SM-like models by setting the flag
UseSM4LoopRGEs = True
in the corresponding model file.
Many thanks to Alexander Bednyakov for providing the expression for
the 4-loop beta function for the strong gauge coupling.
* Feature: Implementing 4-loop effective potential contributions to
the Higgs pole mass in the Standard Model from [arxiv:1508.00912].
The 4-loop contributions are enabled in all FlexibleEFTHiggs models
by default and can be enabled in other SM-like models by setting
the flag
UseHiggs4LoopSM = True
in the corresponding model file.

allFinite() function, which may affect FS output.
FlexibleSUSY 2.0.1 [October, 20 2017]
* Feature: For each FlexibleSUSY the TeX file
/_references.tex is created, which contains \cite{}
commands with references to be cited. Note, that the references to
be cited are model-specific due to the different switches in the
FlexibleSUSY model files.
* Bugfix (commit 682de11c): Include 2-loop gluino contribution in the
extraction of yt from the top pole mass in the split-MSSM, Eq.(4.7)
of arxiv:1312.5220, if UseHiggs3LoopSplit == True.
Thanks to Pietro Slavich.
* Bugfix (commit a783e318): Distinguish between tree- and loop-level
EWSB failures, so problem points where only one fails (but not the
other) get handled properly.
* Bugfix (commits 88009cac, 5ac9366c): Now configure script does not
hang even if Mathematica fails to find a valid license. The script
does not quit even if Mathematica does not meet the version
requirement, unless --enable-meta or --enable-librarylink is given.
Thanks to Anders Kvellestad.
FlexibleSUSY 2.0.0 [October, 10 2017]
* Feature: The weak mixing angle can now be calculated from the muon
decay constant at the full 1-loop level (including flavour mixing
effects) in a wide range of models. 2-loop corrections of the
order O(alpha_em*alpha_s + alpha_t^2) are taken into account, if
applicable.
The method to calculate the weak mixing angle can be chosen in the
model file by setting the variable FSWeakMixingAngleInput to either
Automatic, FSFermiConstant or FSMassW. If FSWeakMixingAngleInput
== FSFermiConstant, then the muon decay constant will be used to
determine the weak mixing angle. If FSWeakMixingAngleInput ==
FSMassW, then the W mass will be used. If FSWeakMixingAngleInput
== Automatic (this is the default), then most precise applicable
method is chosen automatically.
Example:
FSWeakMixingAngleInput = Automatic; (* recommended *)
The variable FSWeakMixingAngleOptions has been removed and can no
longer be used.
* Feature: BSM contributions to the anomalous magnetic moment of the
muon, a_mu, at the 1L level in any given BSM model. Note: Diagrams
with non-SM vector bosons are not taken into account.
In order to let FlexibleSUSY calculate a_mu, the symbol
FlexibleSUSYObservable`aMuon must be written into an SLHA output
block in the ExtraSLHAOutputBlocks variable in the FlexibleSUSY
model file.
Example:
ExtraSLHAOutputBlocks = {
{FlexibleSUSYLowEnergy,
{{21, FlexibleSUSYObservable`aMuon}}}
};
Thanks to Jobst Ziebell.
* Feature: BSM contributions to the electric dipole moment of
fermions at the 1L level in any given BSM model. Note: Diagrams
with non-SM vector bosons are not taken into account.
In order to let FlexibleSUSY calculate the EDM of a fermion F, the
symbol FlexibleSUSYObservable`EDM[F] must be written into an SLHA
output block in the ExtraSLHAOutputBlocks variable in the
FlexibleSUSY model file. If F is a multiplet, the field index must
be specified, for example FlexibleSUSYObservable`EDM[F[1]] for the
first field in the multiplet.
Example:
ExtraSLHAOutputBlocks = {
{FlexibleSUSYLowEnergy,
{{23, FlexibleSUSYObservable`EDM[Fe[1]]},
{24, FlexibleSUSYObservable`EDM[Fe[2]]},
{25, FlexibleSUSYObservable`EDM[Fe[3]]} } }
};
Thanks to Jobst Ziebell.
* Feature: New functions, FSGetProblems[],
FSGetWarnings[] and FSToSLHA[], have been added to
FlexibleSUSY's spectrum generator Mathematica interface. The first
two functions return details about problems / warnings for the
given parameter point. The third one formats the output according
to the SLHA standard.
* Feature: 3-loop beta functions (if available) are calculated in
parallel if multi-threading is enabled. This leads to a ~25% speed
improvement in the MSSM when 3-loop RG running is used.
* Feature: Support for SLHA-2 input block IMEXTPAR.
* Feature: The full 2-loop O(alpha_s^2) corrections to the DR-bar top
and bottom Yukawa couplings [arxiv:hep-ph/0210258,
arxiv:hep-ph/0507139, arxiv:hep-ph/0707.0650] can be added by
setting
UseMSSMYukawa2Loop = True
in the model file.
Thanks to Alexander Bednyakov for providing the expressions.
* Feature: The full 2-loop O(alpha_s^2 + alpha_t*alpha_s +
alpha_b*alpha_s) corrections to the strong coupling
[hep-ph/0509048, arXiv:0810.5101, arXiv:1009.5455] can be added by
setting
UseMSSMAlphaS2Loop = True
in the model file.
Thanks to Ben Allanach for providing the expressions, which have
been extracted from SOFTSUSY 4.0.1.
* Feature: The 2- and 3-loop SM-QCD threshold corrections O(alpha_s^2
+ alpha_s^3) corrections to the strong coupling [hep-ph/0004189]
can be added by setting
UseSMAlphaS3Loop = True
in the model file.
* Feature: The SQLite database output now contains the MS-bar/DR-bar
mass spectrum and mixing matrices, in addition to the pole mass
spectrum.
* Feature: The loop orders of the threshold corrections of the SM(5)
parameters to the BSM model can now be selected individually by
using the flag FlexibleSUSY[24] in the SLHA input file or the
thresholdCorrections variable in the Mathematica interface. The
given value consists of 9 digits, each one representing the
threshold correction loop order of a parameter:
digit position n | default value | parameter
| (prefactor of 10^n) |
-------------------:|---------------------|-------------------
0 | 1 (1-loop) | alpha_em
1 | 2 (2-loop) | sin(theta_W)
2 | 3 (3-loop) | alpha_s
3 | 1 (1-loop) | m_Z
4 | 1 (1-loop) | m_W
5 | 1 (1-loop) | m_h
6 | 3 (3-loop) | m_t
7 | 2 (2-loop) | m_b
8 | 1 (1-loop) | m_\tau
The default value is 123111321, which corresponds to the loop
orders given in the above table.
* Feature: An additional boundary value problem solution algorithm,
based on expanding the soft SUSY breaking or dimensionful
parameters in terms of semi-analytic solutions to the RGEs, can
now be used to calculate the spectrum in a model.
The boundary value solver algorithms to be used in a model can be
specified by setting the variable FSBVPSolvers to be a list
containing all of the desired solvers in the model file. By
default, this is set to FSBVPSolvers = { TwoScaleSolver },
corresponding to only the two-scale solver being enabled.
Example: To enable only the semi-analytic solver instead, the
model file should contain the setting
FSBVPSolvers = { SemiAnalyticSolver };
Currently, the semi-analytic solver can be used in models where
all of the parameters to be expanded are fixed in the same
boundary condition, such as the CMSSM or CNMSSM.
* Feature: The 3-loop corrections to the Standard Model Higgs mass of
the order O(alpha_t^3 + alpha_t^2 alpha_s + alpha_t alpha_s^2) of
[arxiv:1407.4336] can be taken into account by setting
UseHiggs3LoopSM = True;
in the FlexibleSUSY model file. In addition, the pole mass loop
order must be set to a value greater or equal to 3 to switch the
corrections on (SLHA input: FlexibleSUSY[4], Mathematica interface:
poleMassLoopOrder). To switch on/off the individual 3-loop
contributions, the SLHA input flags FlexibleSUSY[26-29] or the
Mathematica symbols
higgs3loopCorrectionAtAsAs
higgs3loopCorrectionAbAsAs
higgs3loopCorrectionAtAtAs
higgs3loopCorrectionAtAtAt
can be used.
* Feature: In the MSSM, the 3-loop corrections O(alpha_t*alpha_s^2)
and O(alpha_b*alpha_s^2) to the Higgs pole mass from Ref.
[arxiv:hep-ph/1005.5709] can be taken into account. The
corrections are taken from the Himalaya package [arxiv:1708.05720].
Himalaya can be downloaded from
https://github.com/jklappert/Himalaya
To build Himalaya, run
$ cd $HIMALAY_PATH
$ mkdir build
$ cd build
$ cmake ..
$ make
where $HIMALAY_PATH is the path to the Himalaya package.
To enable the 3-loop corrections in a FlexibleSUSY model, set the
following flag in the FlexibleSUSY model file:
UseHiggs3LoopMSSM = True;
In addition, we strongly recommend to set
UseHiggs2LoopMSSM = True;
EffectiveMu = \[Mu]; (* chose sign convention for mu parameter *)
UseMSSMYukawa2Loop = True;
UseMSSMAlphaS2Loop = True;
UseMSSM3LoopRGEs = True;
There are already three model files with all these corrections
enabled: MSSMNoFVatMGUTHimalaya, MSSMNoFVHimalaya,
NUHMSSMNoFVHimalaya.
To build the FlexibleSUSY spectrum generator with the 3-loop
corrections from Himalaya, the location of the Himalaya library and
the Himalaya header files must be passed to the configure script:
$ ./configure --with-models=[...] \
--enable-himalaya \
--with-himalaya-incdir=$HIMALAY_PATH/source/include \
--with-himalaya-libdir=$HIMALAY_PATH/build
$ make
To enable the 3-loop corrections at run-time, the following flags
should be set in the SLHA input:
Block FlexibleSUSY
4 3 # pole mass loop order
5 3 # EWSB loop order
6 3 # beta-functions loop order
7 2 # threshold corrections loop order
8 1 # Higgs 2-loop corrections O(alpha_t alpha_s)
9 1 # Higgs 2-loop corrections O(alpha_b alpha_s)
10 1 # Higgs 2-loop corrections O((alpha_t + alpha_b)^2)
11 1 # Higgs 2-loop corrections O(alpha_tau^2)
24 123111221 # individual threshold correction loop orders
25 0 # ren. scheme for Higgs 3L corrections (0 = DR, 1 = MDR)
26 1 # Higgs 3-loop corrections O(alpha_t alpha_s^2)
27 1 # Higgs 3-loop corrections O(alpha_b alpha_s^2)
In FlexibleSUSY's Mathematica interface, the following settings
should be used:
fsSettings -> {
poleMassLoopOrder -> 3, (* FlexibleSUSY[4] *)
ewsbLoopOrder -> 3, (* FlexibleSUSY[5] *)
betaFunctionLoopOrder -> 3, (* FlexibleSUSY[6] *)
thresholdCorrectionsLoopOrder -> 2,(* FlexibleSUSY[7] *)
higgs2loopCorrectionAtAs -> 1, (* FlexibleSUSY[8] *)
higgs2loopCorrectionAbAs -> 1, (* FlexibleSUSY[9] *)
higgs2loopCorrectionAtAt -> 1, (* FlexibleSUSY[10] *)
higgs2loopCorrectionAtauAtau -> 1, (* FlexibleSUSY[11] *)
thresholdCorrections -> 123111221, (* FlexibleSUSY[24] *)
higgs3loopCorrectionRenScheme -> 0,(* FlexibleSUSY[25] *)
higgs3loopCorrectionAtAsAs -> 1, (* FlexibleSUSY[26] *)
higgs3loopCorrectionAbAsAs -> 1, (* FlexibleSUSY[27] *)
}
* Feature: Adding complete 1-loop O(alpha_tau + alpha_b) and complete
2-loop O((alpha_t + alpha_b)^2 + atau^2) threshold corrections for
lambda(MSUSY) to the HSSUSY model file from [arXiv:1703.08166].
Many thanks to Pietro Slavich and Emanuele Bagnaschi for providing
the expressions.
Note: 5 new flags are introduced to enable/disable the individual
2-loop corrections. In the SLHA input the flags which control the
inclusion of 2-loop corrections are:
Block EXTPAR # Input parameters
100 2 # LambdaLoopOrder
101 1 # TwoLoopAtAs
102 1 # TwoLoopAbAs
103 1 # TwoLoopAtAb
104 1 # TwoLoopAtauAtau
105 1 # TwoLoopAtAt
In the Mathematica interface the flags which control the inclusion
of 2-loop corrections are:
handle = FSHSSUSYOpenHandle[
fsModelParameters -> {
...
LambdaLoopOrder -> 2,
TwoLoopAtAs -> 1,
TwoLoopAbAs -> 1,
TwoLoopAtAb -> 1,
TwoLoopAtauAtau -> 1,
TwoLoopAtAt -> 1
}
]
* Feature: Adding the new input parameter DeltaEFT to the HSSUSY
spectrum generator to allow the user to estimate the EFT
uncertainty. Each 1-loop term in the threshold correction for
lambda(MS) is multiplied by the factor
(1 + DeltaEFT v^2/MS^2)
Thus, the standard calculation of HSSUSY is obtained by DeltaEFT =
0 (default). Set DeltaEFT = 1 to obtain an alternative Higgs pole
mass with a shifted threshold correction to estimate the effect of
the missing terms of O(v^2/MS^2).
* Change: The interface for adding constraints and matching
conditions to the Two_scale_solver class has been simplified.
Constrains and matching conditions are now added using the add()
function. The added constraints and matching conditions are
imposed in the given order.
Example: To first impose the low-scale, then the high-scale and
finally the susy-scale constraint call
solver.add(&low_scale_constraint, &model);
solver.add(&high_scale_constraint, &model);
solver.add(&susy_scale_constraint, &model);
* Change: The readability of the vertices and the self-energies has
been improved by using the SUM() and IF() macros.
* Change: In FlexibleEFTHiggs models, the Standard Model parameters
are written to the SLHA output in addition to the BSM parameters.
* Change: The return value of FSCalculateSpectrum[] and
FSCalculateObservables[] has been changed. They have now
the structure
{ -> { model parameters ... } }
In FlexibleEFTHiggs models, the Standard Model parameters are
returned in addition and the output has the form
{ -> { model parameters ... },
StandardModel -> { ... } }
* Change: In multi-threading mode pole masses are calculated using a
thread pool instead of spawning threads manually. This avoids over
subscription on machines with very few CPU cores.
* Change: The performance of FlexibleEFTHiggs has been improved by
around 20% by using a faster implementation of the B1 loop function
in the limit of vanishing momentum and non-zero masses.
* Change (commit b5cad9e): Automatically chose the maximum number of
EWSB and pole mass iterations based on the user-defined precision
goal. This change leads to a performance improvement for some
parameter points where the EWSB equations cannot be fulfilled.
* Change: The legacy module and most SOFTSUSY components have been
removed.
* Change: All gauge couplings written to the GAUGE block in the SLHA
output are now unnormalized. Before, only the hypercharge gauge
coupling was written as unnormalized in the GAUGE block. Note:
Internally, FlexibleSUSY uses normalized gauge couplings only. In
order to write the normalized gauge couplings to the SLHA output, a
separate output block should be created.
Example:
ExtraSLHAOutputBlocks = {
{GAUGENORM, (* contains normalized gauge couplings *)
{{1, g1},
{2, g2},
{3, g3},
{4, gN} } }
};
* Change (commit 9bfd5f1): tan(beta)-enhanced contributions to the
down-lepton Yukawa couplings are now resummed.
* Change (commit 52faaa7): The symbol SUSYScaleMatching has been
renamed to MatchingScaleInput, to express that it is imposed at the
matching scale, which is in general not equal to the SUSYScale.
* Change: Update to GM2Calc 1.3.3.
* Bugfix (commits be8f35b, 3432967): Improve the stability of the
algorithm which solves the EWSB conditions. The more stable
algorithm leads to a faster convergece of the overall iteration in
scenarios where the EWSB conditions don't have a solution or the
solution is hard to find.
Thanks to Peter Athron and Pat Scott.
* Bugfix (commit 0cb4042): Matrix products of the form A*B in the
boundary conditions are now interpreted as element-wise products
(as in Mathematica). For genuine matrix products use MatMul[A,B]
or A.B.
* Bugfix (commits 9738ba1, 118a9a70): Catch potential numerical
instabilities during mass matrix diagonalization, which may result
in eigenvectors with magnitude larger than 1.
FlexibleSUSY-1.7.5 [September, 05 2017]
* Bugfix (commit 03e9265): Correcting wrong vertex between
chargino-smuon-neutrino and chargino-muon-sneutrino in muon decay.
Thanks to Markus Bach.
* Bugfix (commit f3f3850): Correcting coefficient in complex
dilogarithm.
* Bugfix (commit d8d8c0c): Make LibraryLink Set[] functions accept
matrix-valued parameters.
* Bugfix (commit 072be7e): Enable 3-loop RGEs in HSSUSY by default.
FlexibleSUSY-1.7.4 [April, 12 2017]
* Bugfix (commit f434e30): Rename internal IndexSum symbol which
conflicts with SARAH version 4.11.0 and higher.
* Bugfix (commit b8d5dcf): Correcting gauge-dependent term in 2-loop
beta function of SM vacuum expectation value after a corresponding
bugfix in SARAH 4.11.0. This bugfix affects the Higgs mass
prediction with FlexibleEFTHiggs by around 10 MeV.
FlexibleSUSY-1.7.3 [February, 27 2017]
* Change (commit 43bb03a): FlexibleSUSY now aborts the code
generation if the user tries to fix an unknown parameter in a
constraint. (Before this commit, FlexibleSUSY did only print a
warning.)
* Change (commit cff40dd): Catch non-numeric user input to the
LibraryLink interface functions.
* Bugfix (commit 4a5ada7): Adding missing return statement in
function recalculate_mw_pole(). This bug was only present if the W
pole mass is used as input (not GF).
* Bugfix (commit bd5ee68): Correctly handle whitespace in directory
names inside the configure script and search for headers in $CPATH
and $CPLUS_INCLUDE_PATH .
Thanks to Joshua Ellis.
* Bugfix (commit bc770ae): Ensure that phase of (complex) mu
parameter has magnitude 1 in the CMSSMCPV.
Thanks to Jobst Ziebell.
* Bugfix (commit beb4683): Accept SLHA output blocks specified as
strings (not symbols).
Thanks to Joshua Ellis.
* Bugfix: Implement missing limits of threshold correction functions
from arXiv:1407.4081.
* Bugfix (commit 581080f): Catch further NaNs from inside the MSSM 2L
Higgs mass routines of Pietro Slavich.
FlexibleSUSY-1.7.2 [December, 15 2016]
* Feature (commit b052e35): New flag FlexibleSUSY[23] to disable the
pole mass calculation of the non-SM particles. This flag is useful
in FlexibleEFTHiggs, when the SUSY scale is so high that the non-SM
particle masses become unreliable or tachyonic: If a non-SM pole
mass becomes tachyonic (maybe because the loop corrections become
too large) FlexibleSUSY would flag the given parameter point as
unphysical. However, one might still be interested in the value of
the SM-like Higgs mass, which is valid in FlexibleEFTHiggs even for
very large SUSY scales. In such a case FlexibleSUSY[23] could be
set to 0 to suppress the calculation of the non-SM pole masses.
* Feature (commit 998f11e): Slightly improved speed of the RG
running.
* Change (commit 189f508): Speed-up the calculation of the 2L Higgs
mass corrections in the MSSM and NMSSM, if multi-threading is used,
by locking the mutex only for the O(at*at) corrections.
* Change: The limits sin(2*theta) = 0 and m_stop1 = m_stop2 have been
implemented for the 2L O(at*as) Higgs pole mass corrections in the
MSSM to avoid numeric instabilities.
* Bugfix (commit 20f169f): Re-calculate W pole mass in
FlexibleEFTHiggs. Before this commit the electroweak gauge
couplings in FlexibleEFTHiggs are wrong in scenarios with very
small alpha_em(MZ) (< 1/1000) and/or a small Z pole mass (< 10
GeV).
* Bugfix (commit 38d17ca): More reliable convergence criterion for
FlexibleEFTHiggs for large SUSY scales. Before this commit, only
the running BSM masses (at the SUSY scale) have been used as
convergence criterion. However, they tend to converge very fast,
compared to the running SM masses at the electroweak scale. For a
more reliable convergence criterion, now both the running BSM and
SM masses are used.
* Bugfix (commits 5e1b6b3, cc5bfae): Correction of the 2-loop and
3-loop QCD corrections to the top pole mass in the Standard Model
in the MS-bar scheme. Refs. [hep-ph/9803493, hep-ph/9912391,
hep-ph/9911434] have expressed the relation between the top pole
mass and the MS-bar mass in terms of Log[Q^2/Mt^2], where Mt is the
top pole mass. Before these commits, FlexibleSUSY used the
expressions from theses references, but wrote result in terms of
Log[Q^2/mt^2], where mt is the MS-bar mass, while not accounting
for the difference between Mt and mt in the logarithms. This
bugfix affects the Higgs pole mass at the 3-loop level.
* Bugfix (commit cecff4b): Flag scalar or vector boson gauge singlet
tachyons.
* Bugfix (commit 4a3fb5b): Input tan(beta) at the SUSY scale, instead
of at the matching scale in the FlexibleEFTHiggs model files. This
difference matters when the (unphysical) matching scale is varied
through FlexibleSUSY[19].
* Bugfix (commit c35dcb2): Fixed linking problem of the LibraryLink
on Mac.
* Bugfix (commits a643be5, cc9ebf1): Avoid function call ambiguities
when multiple LibraryLink libraries are loaded into Mathematica at
the same time.
* Bugfix (commit 1f8e135): Correcting FSSet[] function for
models with matrix-valued parameters.
* Bugfix (commit 4097708): The generated LibraryLink files are now
added to the model tarball created by `make pack--src'.
FlexibleSUSY-1.7.1 [October, 15 2016]
* Change (commit b1efa8c): Updated to GM2Calc 1.3.0.
* Change (commit 05d8e11): The loop order of the BSM top Yukawa
coupling at the scale M_SUSY in FlexibleEFTHiggs is now set
automatically to match the loop order of the matching condition
from the SM to the BSM model.
Before this commit, the user had to set FlexibleEFTHiggs[13] = 0
and FlexibleEFTHiggs[20] = 1 when yt(BSM) should be calculated
using 1L QCD corrections. Analogous, the user had to set
FlexibleEFTHiggs[13] = 1 and FlexibleEFTHiggs[20] = 2 when yt(BSM)
should be calculated using 2L QCD corrections. Now,
FlexibleEFTHiggs[13] is set automatically to FlexibleEFTHiggs[20] -
1 when yt(BSM) is calculated in FlexibleEFTHiggs.
* Change (commit b533d67): Faster calculation of effective vertices h
-> photon photon and h -> gluon gluon.
* Bugfix (commit 8b04191): Improve numerical stability of low-scale
iteration which determines the SM(5) parameters by using a higher
RG running precision than the precision goal for the convergence.
* Bugfix (commit 44d2f01): Print SLHA output even if QedQcd class
throws an exception.
FlexibleSUSY-1.7.0 [September, 19 2016]
* Feature: FlexibleSUSY is now able to generate custom spectrum
generators using the FlexibleEFTHiggs method described in
[arXiv:1609.00371]. The following FlexibleEFTHiggs example models
are provided: CMSSMEFTHiggs, MSSMEFTHiggs, MSSMNoFVEFTHiggs,
NMSSMEFTHiggs, NUHMSSMaltEFTHiggs, MRSSMEFTHiggs, E6SSMEFTHiggs. A
documentation of the new model file options to create a custom
FlexibleEFTHiggs spectrum generator can be found in
doc/html/FlexibleEFTHiggs.html .
* Feature: FlexibleSUSY now provides a Mathematica interface for the
generated spectrum generators. For each model, an example
Mathematica script
models//run_.m
is generated, which illustrates the usage. The documentation of
the Mathematica interface and several examples can be found in
FlexibleSUSY's HTML documentation. Please see the section
"Creating the soucre code documentation" in the README file for a
description about how to generate the documentation.
* Change: The configure options for creating dynamic libraries and
statically linked executable have been changed. By default, static
FlexibleSUSY libraries and dynamically linked executables are
created.
To generate shared FlexibleSUSY libraries, run
$ ./configure --enable-shared-libs ...
To generate statically linked executables, run
$ ./configure --enable-static ...
Please refer to the README file for more information.
* Bugfix (commit 39f8d36): Fix segfault when multi-threading is used
in statically linked executables.
* Bugfix (commit 3126ac1): Catch NaNs from inside the MSSM 2L Higgs
mass routines of Pietro Slavich.
* Bugfix (commit b6db614): Correcting 2-loop self energy O(alpha_t^2)
in the Standard Model. Before, Eq. (20) of arxiv:1205.6497 has
been used. However, this is incorrect, because it includes 2-loop
contributions from the momentum iteration of the 1-loop self
energy, which would be double counted, because FlexibleSUSY already
does a momentum iteration of the 1-loop self energy. To fix this,
Eq. (20) of arxiv:1504.05200 has been used, which does not include
these 2-loop pieces.
FlexibleSUSY-1.6.1 [August, 28 2016]
* Bugfix (commit db67c81): Fix compilation with --disable-threads .
FlexibleSUSY-1.6.0 [August, 27 2016]
* Feature (commit 4e9ef56): Allow user to access the beta-functions
of the model parameters on the r.h.s. of the constraints. BETA[p]
represents the beta function of the parameter p using the loop
level given in the SLHA input. BETA[l,p] represents the l-loop
beta function of the parameter p.
Example in the SM:
HighScaleInput = {
{\[Lambda], BETA[g1] + BETA[g2] + BETA[1,Yu][3,3]}
};
* Feature (commit 5e0bca1): Allow user to add 3-loop QCD corrections
of [arxiv:hep-ph/9912391] when calculating the top pole mass in
non-SUSY models. The 3-loop QCD corrections are added if the flag
FlexibleSUSY[13] is set to 2 and the pole mass loop order,
FlexibleSUSY[4], is set to a value > 2.
FlexibleSUSY[13] = 0 and FlexibleSUSY[4] > 0: 1L QCD correction
FlexibleSUSY[13] = 1 and FlexibleSUSY[4] > 1: 2L QCD correction
FlexibleSUSY[13] = 2 and FlexibleSUSY[4] > 2: 3L QCD correction
* Feature (commits 98bc536, e8fd56a): Speed up of the RG running in
models with very complicated beta functions.
* Change (commit 728b5ea): `make clean' no longer removes generated
source files to avoid the need to re-generate them. To remove the
generated files use either
$ make clean--src # deletes generated files for
or
$ make clean-generated # deletes all generated files
* Bugfix (commit a5342eb): Avoid non-portable use of sed in
createmodel. This fixes `make install-src' on Mac.
* Bugfix (commit 44b31fa): Fix potential race condition when
different model classes that make use of the (N)MSSM 2-loop Higgs
mass routines of P. Slavich call calculate_spectrum() at the same
time.
* Bugfix (commit 0d08b99): Do not try to generate non-squared unit
matrices for beta function expressions that must be splitted.
Non-squared unit matrices did appear for non-squared matrix-valued
parameters, as for example T[hE] in the SE6SSM.
Thanks to Dylan Harries.
FlexibleSUSY-1.5.1 [July, 12 2016]
* Bugfix (commit 63f5361): Fix numerical instability of SOFTSUSY's B1
function in parameter regions with p << m1,m2 and m1 close to m2.
* Bugfix (commit fc6d509): Fix makefile bug in the tarball by
shipping all .m files that appear in the list of dependencies for
the generated C++ code.
FlexibleSUSY-1.5.0 [June, 29 2016]
* Feature: Write phases to SLHA output if a SLHA output block is
defined for them in the SARAH model file.
Thanks to Dylan Harries.
* Feature: Allow the user to calculate the pole masses at a fixed
renormalisation scale at run-time, which is different from the one
set by the SUSYScale model file variable. The fixed
renormalisation scale can be given via the FlexibleSUSY[17] entry
in the SLHA input. FlexibleSUSY[17] is equivalent to
SPhenoInput[33] in SPheno.
* Feature: Updated to GM2Calc 1.2.0.
* Bugfix (commit 9a2d576): Fix compilation error due to ambiguous
overload of operator<< .
Thanks to Dylan Harries.
* Bugfix (commits fc748be, 9654a52): Fix compilation in case Greek
Symbols appear in If[] or Which[] functions in the model file.
Thanks to Dylan Harries.
* Bugfix: Fix compilation with g++ 4.4.7.
Thanks to Dylan Harries.
* Bugfix (commit 6f5e38e): Correcting convergence criterion in the
iteration which determines the 1st and 2nd generation running
fermion masses in the SM(5) at the low-energy scale. After this
correction, the running 1st and 2nd generation SM(5) fermion masses
differ from SOFTSUSY by less than 0.5% at the electroweak scale.
FlexibleSUSY-1.4.2 [May, 09 2016]
* Bugfix: Correcting handling of spaces in configure script if
/bin/sh is /bin/dash.
FlexibleSUSY-1.4.1 [May, 09 2016]
* Feature: Tab-completion for FlexibleSUSY's spectrum generators and
scripts in the bash.
Usage:
. utils/install-bash_completions.bash
* Feature: For each model an example SLHA input file is generated,
which is located at models//LesHouches.in._generated
* Feature (commit 2b95522): Allow user to provide specific location
to libpthread using the --with-pthread-libdir= option.
* Change: The algorithm to determine the running fermion masses and
gauge couplings has been replaced by a more secure one. The new
algorithm performs an iteration between 2 GeV and MZ to fix all
input parameters at their scale. The new algorithm leads to
running 1st and 2nd generation quark masses, which differ from
SOFTSUSY by around 3%.
* Bugfix (commit 59b867d): Avoid singularity in the limit MSU^2 /
M3^2 -> MSQ^2 / M3^2 in HSSUSY.
* Bugfix (commit f3864b8): Catch exception from SOFTSUSY's QedQcd
class which are triggered when the input value of Mt_pole is chosen
to be smaller than MZ_pole.
* Bugfix (commit 077c5b9): Fixing check for SARAH installation with
Mathematica 10.
* Bugfix (commit e9954d6): Fixing numerical instability of SOFTSUSY's
B0 and B22 functions for very heavy spectra and external small
momenta.
* Bugfix (commits bcb99bc - 8b5d87e): Fixing compilation error for
models which don't have input parameters.
* Bugfix (commits 637d099, 8b3a94f, 2e3a972): Fixing `make
install-src' in case the path to the FlexibleSUSY contains spaces.
* Bugfix (commits ced2072, 8bc8fdd): Adding support for further
debian-based multi-architecture linux distributions in the
configure script.
FlexibleSUSY-1.4.0 [March, 08 2016]
* Feature: Allow the user to chose the loop order of the RGEs to be
generated by SARAH. This is useful in pure low-energy models,
where no RGE running is needed, or in very complex models, where
the generation of the RGEs takes a very long time.
The RGE loop order can be set in the model file using the
`FSRGELoopOrder' variable.
Example:
FSRGELoopOrder = 0; (* no RGEs generated *)
FSRGELoopOrder = 1; (* only 1-loop RGEs generated *)
FSRGELoopOrder = 2; (* 1- and 2-loop RGEs generated (default) *)
Note: The RGE loop order can also be specified at run-time in the
SLHA input block FlexibleSUSY[6] .
* Feature: FlexibleSUSY no longer requires that the weak mixing angle
and potential Z-Z' mixing angles are provided in terms of
Lagrangian density parameters (gauge couplings etc.). Instead,
FlexibleSUSY makes use of the DependenceSPheno specification given
in the SARAH model file to calculate these mixing angles
numerically. In this way the effect of gauge boson mixings in
models with extended gauge groups can be taken into account
automatically.
Note: If the weak mixing angle is to be fixed at the low-energy
scale by the running W and Z masses (see FSWeakMixingAngleOptions
option) in order to determine the electroweak gauge couplings, then
an expression for it has to be given in either DependenceNum or
FSWeakMixingAngleExpr .
Example for the MRSSM:
(* determine weak mixing angle from W and Z masses *)
FSWeakMixingAngleOptions = FSSetOption[
FSWeakMixingAngleOptions,
FSWeakMixingAngleInput -> FSMassW
];
(* need to provide expression for weak mixing angle *)
FSWeakMixingAngleOptions = FSSetOption[
FSWeakMixingAngleOptions,
FSWeakMixingAngleExpr -> ArcSin[Sqrt[1 - (Mass[VWm]^2 - g2^2*vT^2)/Mass[VZ]^2]]
];
Important note: In the SARAH model file a mass ordering of the
vector bosons is assumed. For example, the statement
DEFINITION[EWSB][GaugeSector] = {
{{VB,VWB[3],VBp}, {VP,VZ,VZp}, ZZ},
...
};
assumes MVP < MZ < MZp. Thus, the user has to make sure that the
studied parameter region leads to Photon, Z and Z' masses which are
in agreement with the relation MVP < MZ < MZp. Otherwise, the
calculated Z and Z' masses will be incorrect. If a parameter
region shall be studied where MVP < MZp < MZ, then the ordering of
vector bosons in the SARAH model file has to be changed to
DEFINITION[EWSB][GaugeSector] = {
{{VB,VWB[3],VBp}, {VP,VZp,VZ}, ZZ},
...
};
* Feature: By setting the entry FlexibleSUSY[16] = 1 in the SLHA
input file, the user can force majorana fermion masses to be
positive. In this case, the corresponding mixing matrix is not
purely real and its imaginary part will be written to the output in
addition. Note, that setting FlexibleSUSY[16] = 1 is therefore a
violation of the SLHA standard.
* Feature: FlexibleSUSY calculates the effective 1-loop couplings of
the CP-even and CP-odd Higgs -> photon + photon and Higgs -> gluon
+ gluon.
Author: Dylan Harries
For each model the _effective_couplings class is generated
and can be used at the C++ level to calculate the effective
couplings. In order to write the effective couplings to the SLHA
output, extra SLHA output blocks have to defined in the
FlexibleSUSY model file, which contain the symbols
FlexibleSUSYObservable`CpHiggsPhotonPhoton
FlexibleSUSYObservable`CpHiggsGluonGluon
FlexibleSUSYObservable`CpPseudoScalarPhotonPhoton
FlexibleSUSYObservable`CpPseudoScalarGluonGluon
Example:
Definition of an extra SLHA output block named `EFFHIGGSCOUPLINGS',
containing the effective 1-loop CP-even and CP-odd Higgs -> photon
+ photon and Higgs -> gluon + gluon couplings:
ExtraSLHAOutputBlocks = {
{EFFHIGGSCOUPLINGS,
{{1, FlexibleSUSYObservable`CpHiggsPhotonPhoton},
{2, FlexibleSUSYObservable`CpHiggsGluonGluon},
{3, FlexibleSUSYObservable`CpPseudoScalarPhotonPhoton},
{4, FlexibleSUSYObservable`CpPseudoScalarGluonGluon} } }
};
The calculation of the effective couplings can be disabled (or
enabled) by setting the flag FlexibleSUSY[15] to 0 (or 1) in the
SLHA input file.
* Feature: Allow the user to temporarily re-define model parameters
in the boundary conditions, which are restored to their original
values after the calculations in the boundary condition has been
finished.
Example: Temporarily scale the gauge coupling g1 by a factor 1/2
and set the up-quark Yukawa coupling to zero:
LowScaleInput = {
{Temporary[g1], g1 / 2},
{Temporary[Yu[1,1]], 0},
...
};
* Feature: The three THDM-like models, which have been used in
arxiv:1512.07761, are provided. The models implement the 1- and
2-loop threshold corrections of arxiv:1508.00576 and
arxiv:hep-ph/9307201. The models are named:
* THDMIIMSSMBC (THDM with boundary condition to the MSSM)
* HTHDMIIMSSMBC (THDM + Higgsinos with boundary condition to the
MSSM)
* HGTHDMIIMSSMBC (THDM + Higgsinos + gauginos with boundary
condition to the MSSM)
* Feature: In non-SUSY models the 3-loop (Standard Model) QCD
corrections to the MS-bar Yukawa coupling of the order O(alpha_s^3)
[arxiv:hep-ph/9911434, arxiv:hep-ph/9912391] are added
automatically. They are taken into account at run-time if the
threshold correction loop (FlexibleSUSY[7]) order is set to a value
> 2 in the SLHA input file.
The generation of 3-loop QCD corrections can be disabled by setting
in the model file
UseYukawa3LoopQCD = False;
* Change (commit f2f913e, 002c904): When threshold corrections are
disabled, the charged lepton and top quark pole masses are used to
determine the corresponding Yukawa couplings. Before commit
f2f913e, the running Standard Model masses were used. This change
makes it easier to compare the mass spectrum with SPheno when
threshold corrections are disabled.
* Change (commit 1c7e4a7): The 2-loop QCD contribution to the top
Yukawa coupling [hep-ph/0210258 Eq. (60)-(61), hep-ph/9803493
Eq. (17)] is taken into account only if the threshold correction
loop order (flag FlexibleSUSY[7]) is set to a value > 1. Before
commit 1c7e4a7 the 2-loop QCD contribution was always taken into
account and could not be disabled. This change allows the user to
consistently disable 2-loop contributions.
* Bugfix (commit f7ff872): Support models which have couplings
proportional to the epsilon tensor in color space.
* Bugfix (commit 8c1ca39): Enabling support to use
LowEnergyConstant[MZ] as scale for the susy-scale contraint.
LowEnergyConstant[MZ] will be replaced in the C++ code by the
user-defined SLHA input value of the Z pole mass.
Example:
SUSYScale = LowEnergyConstant[MZ];
* Bugfix (commit 0a7934e): Fix compilation error in models in which a
multiplet exists, which consists only of Goldstone bosons.
* Bugfix (commit a87042f): Rename enum entries for matrices to
prevent compilation errors in models which have mixing matrices
larger than 10x10.
* Bugfix (commit 61fb1ca): Fix compilation errors in models which
don't contain SM-like neutrinos.
* Bugfix (commit 919347d): Correcting the phase of Dirac fermion
singlets if their mass is less than zero: Before commit 919347d,
the phase of Dirac fermion singlets was set to e^(i Pi/2) if their
mass is less than zero, which is wrong, because in SARAH only one
Weyl component of the Dirac spinor receives a phase. After this
commit, the phase of Dirac fermion singlets is set to e^(i Pi) if
their mass is less than zero.
* Bugfix (commits 060b492, a6f7741, 306385b): Implement massless
limits in C0, D0 and D27 functions.
* Bugfix (commits d62886d): Ensure that only Standard Model goldstone
bosons are removed to obtain "heavy" W and Z self-energies.
* Bugfix (commits 60d68af): Fix compilation error in models where the
left-handed electron and neutrino mass matrices are of equal size,
but larger than 3x3.
FlexibleSUSY-1.3.2 [January, 10 2016]
* Bugfix (commit d76ca79): Fix compilation error with Eigen
3.3-beta1.
FlexibleSUSY-1.3.1 [January, 08 2016]
* Bugfix (commit aa8dc76): Re-enable the output of gauge eigenstate
masses of 1st and 2nd generation sfermions in the CMSSMNoFV for
SLHA-1 compatibility.
FlexibleSUSY-1.3.0 [January, 08 2016]
* Feature: The output of the spectrum generator can be written into
an SQLite database using the --database-output-file= option. At
the C++ level, a to_database() and from_database() function is
provided for each model, which write/read a model object (including
the DR-bar parameters and the pole mass spectrum) to/from a
database file.
Example:
$ models/CMSSM/run_CMSSM.x \
--slha-input-file=model_files/CMSSM/LesHouches.in.CMSSM \
--slha-output-file= --database-output-file=point.db
Example using the scan script:
$ utils/scan-database.sh \
--spectrum-generator=models/CMSSM/run_CMSSM.x \
--slha-input-file=model_files/CMSSM/LesHouches.in.CMSSM \
--scan-range=MINPAR[3]=1~30:21 \
--database-output-file=scan.db
* Feature: Models can now be matched to the Standard Model at Q =
MZ_pole, Q = MT_pole or any other dynamically calculated scale, as
MT_DRbar for example.
To match at MZ_pole set in the model file: LowScale = LowEnergyConstant[MZ]
To match at MT_pole set in the model file: LowScale = LowEnergyConstant[MT]
To match at MT_DRbar set in the model file: LowScale = M[Fu[3]],
depending on your chosen name for the top quark.
* Feature: 3-loop beta-functions can now be used in the real MSSM.
To enable the 3-loop MSSM beta-functions, set UseMSSM3LoopRGEs =
True; in the model file (enabled by default in all real MSSM models
that are shipped with FlexibleSUSY). The expressions have been
obtained from http://www.liv.ac.uk/~dij/betas/allgennb.log and
include family mixing.
Note: The 3-loop beta-functions for the vacuum expectation values
vu and vd are not available so far. Furthermore, the 3-loop MSSM
beta-functions miss the "tadpole" contributions corresponding to
the renormalisation of the Fayet-Iliopoulos D-term, see the note in
Section 2, page 4 of arxiv:hep-ph/0308231 .
* Feature: The anomalous magnetic moment of the muon, (g-2)/2, can be
calculated in all MSSM models without sfermion flavour violation
(e.g. the MSSMNoFV and CMSSMNoFV). The calculation is performed
with GM2Calc 1.1.0 [arXiv:1510.08071] up to the 2-loop level
including tan(beta) resummation.
In order to enable the calculation of (g-2)/2, the symbols
FlexibleSUSYObservable`aMuonGM2Calc
FlexibleSUSYObservable`aMuonGM2CalcUncertainty
have to be added to ExtraSLHAOutputBlocks variable in the
FlexibleSUSY model file (they are already added in the MSSMNoFV and
CMSSMNoFV example models). In addition, the SLHA input file entry
FlexibleSUSY[15] has to be set to 1 to perform the calculation. If
FlexibleSUSY[15] is set to 0, (g-2)/2 is not calculated.
* Change (commit d553af8): No SLHA output is written if the option
--slha-output-file= is set to the empty string. To write the SLHA
output to stdout, set --slha-output-file=- (this is the default).
* Change (commit ac70fec): In the SM the Higgs pole mass is no longer
calculated at the scale Qin (= the scale where lambda is input),
but at the scale Q = M_top.
* Bugfix (commit 1b4fc20): Correcting W contribution in beta-function
of alpha_em in the SM with 5 active quark flavours.
Imported from SOFTSUSY (commit 0139daa).
* Bugfix (commit d7dbeb6): Adding neutrino charge, Qv, to list of
input parameters in the UMSSM. This fixes a compilation error with
SARAH 4.6.0.
* Bugfix (commit f1752a7): Correcting the trilinear couplings and the
effective mu parameter in the NMSSMRUN SLHA output block in the
models: NMSSM, NMSSMCPV, NUTNMSSM, SMSSM and NUTSMSSM.
* Bugfix (commit 9ccdb4d): Workaround a SARAH issue where the list
SARAH`Masses[EWSB] contains replacement rules of the form `0 ->
MassGiven[X]', instead of `Mass[X] -> MassGiven[X]'. Due to this
issue some massless particles have been missing in FlexibleSUSY
before commit 9ccdb4d.
FlexibleSUSY-1.2.4 [October, 27 2015]
* Change (commit 33af37c): The spectrum generator, run_.x,
will no longer overwrite the user-given input parameters of the
SMINPUTS block.
* Bugfix (commit 9067f3a): There was an internal programming error in
the meta code concerning the assignment of tadpole diagrams to the
Higgs fields, which resulted in a compilation error in the SSM.
Thanks to John McDowall.
* Bugfix (commit 77d2a86): Ensure that in the calculation of the pole
mass of a fermion singlet the prefactor of the self-energies is the
positive tree-level mass. Before commit ce1ef83, the prefactor of
the gluino self-energies in MSSM for example was the soft-breaking
parameter M3. If M3 < 0 the gluino pole mass was not calculated
correctly.
Thanks to Dylan Harries and Roman Nevzorov.
FlexibleSUSY-1.2.3 [October, 18 2015]
* Feature: Adding support for If[] and Which[] statements at the
r.h.s. of contraints. In addition, the IsClose[a,b,eps] and
IsCloseRel[a,b,eps] functions have been added to allow for a
comparison of parameters.
* Feature: New model SplitMSSM, which implements low-energy EFT of
the MSSM where the sfermions and one Higgs doublet have been
integrated out. The model implements the 1- and 2-loop matching
conditions from arxiv:1407.4081. The Higgs pole mass is calculated
at complete 1-loop order plus 2-loop contributions O(alpha_t^2) and
O(alpha_t alpha_s) from arxiv:1205.6497 plus 3-loop leading-log
contribution from the gluino O(alpha_t alpha_s^2)
(arxiv:1312.5220).
* Feature: New model HSSUSY, which implements a high-scale SUSY
scenario, where the sfermions, the gauginos, the Higgsinos and one
Higgs doublet have been integrated out, leaving the Standard Model
as low-energy EFT. The model uses the 3-loop Standard Model RGEs
(arxiv:1303.4364, arXiv:1307.3536) and implements the 1- and 2-loop
matching conditions to lambda(MSUSY) from arxiv:1407.4081.
Furthermore, the 1-loop matching conditions O(alpha_b) and
O(alpha_tau) as well as the 2-loop matching condition O(alpha_t^2)
from SUSYHD (arxiv:1504.05200) are implemented. The Higgs pole
mass is calculated at complete 1-loop order plus 2-loop
contributions O(alpha_t^2) and O(alpha_t alpha_s) from
arxiv:1205.6497. The calculation of the Higgs pole mass in the
HSSUSY model coincides with the one obtained with SUSYHD 1.0.2 with
a relative deviation of < 0.06%.
* Feature: Allow adding 3-loop gluino contribution to Higgs
self-energy in split-SUSY models with a physical singlet Higgs.
The 3-loop gluino contribution is enabled by default in the
SplitMSSM.
* Change (commit f7cd242): The `test' and `examples' modules are no
longer loaded into the makefile by default. To load them, run
./configure --with-optional-modules="test,examples"
* Change (commit e86d23a): The FlexibleSUSY test suite is no longer
shipped with the release tarball. It can be obtained from the
official git repository at
https://github.com/FlexibleSUSY/FlexibleSUSY .
* Change (commit 372bb96): Use FlexibleSUSY's own dependency file
generator instead of using the corresponding compiler capabilities.
* Bugfix (commit 20e88db): Use correct self-energy for 1st and 2nd
generation charged leptons in *NoFV models. Before commit 20e88db,
the (heavy) tau self-energy was used to convert the running MS-bar
electron and muon masses to DR-bar masses in *NoFV models.
Corresponding test case:
test_CMSSMNoFV_low_scale_constraint::test_delta_Yf()
FlexibleSUSY-1.2.2 [September, 08 2015]
* Feature: The scale at which the EWSB output parameters are fixed
can now be chosen by the user via the FSSolveEWSBFor[{...}] symbol.
By default, the susy-scale is chosen.
* Change (commit 5b9d653): If ./configure is run without the
`--with-models=' argument, no models will be build. In
former FlexibleSUSY versions if the `--with-models='
argument was missing, all models were build.
* Bugfix (commit 5530bf9): Defining a scale to be a running mass, for
example SUSYScale = M[hh], resulted in a compilation error.
* Bugfix (commits 2d6c0d2, 87cfe28): use SLHA input value of the Z
pole mass as low-energy scale, instead of the hard-coded value MZ =
91.1876 GeV.
* Bugfix (commit 1ac0aa0): Use math/physics index convention (index
starting with 1) in the comments of the extra user-defined SLHA
output blocks.
* Bugfix (commit 0737c4d): Properly convert greek symbols in function
arguments. Fixes #5. Thanks to Dylan Harries.
* Bugfix (commit f4eed5d): Put class Complex into softsusy namespace
to avoid ambiguities in operator*(). Fixes #6. Thanks to Dylan
Harries.
FlexibleSUSY-1.2.1 [July, 07 2015]
* Feature: The model name is printed in SPINFO[5] and the SARAH
version is printed in SPINFO[9].
* Bugfix (fea4d59): The MODSEL block was not read if SLHA input is
passed to the spectrum generator via stdin. Thanks to Peter

FlexibleSUSY-1.2.0 [June, 26 2015]
* Feature: Allow the user to add 3-loop beta-functions in the SM.
The beta-functions are taken from SUSYHD v1.0.1 (arXiv:1504.05200)
and arxiv:1303.4364.
* Feature: Allow the user to add 2-loop Higgs self-energy corrections
O(alpha_t^2 + alpha_t alpha_s) in the SM. The self-energy
corrections were taken from arxiv:1205.6497.
* Feature: Allow the user to provide SLHA input via stdin if the SLHA
input file name is set to - .
Example:
$ cat model_files/CMSSM/LesHouches.in.CMSSM | \
models/CMSSM/run_CMSSM.x --slha-input-file=-
* Feature: Allow the user create standalone executables that don't
depend on dynamically linked libraries. See README for more
details.
* Bugfix (commit 3843ea7): Rewrite pole mass tachyon check to fix a
confusion between goldstone and Higgs bosons in the CP-violating
MSSM.
* Bugfix (commit e2009f7): Adding missing declaration of input
parameters in the generated DependenceNum functions. This fixes a
compilation error in the NE6SSM or the UMSSM if ThetaWp is set to
an expression that involves the charges.
* Bugfix (commits d80c30f, e6c8dda): Correcting input scale of
tan(beta) in the lowNMSSM according to SLHA-2 convention. The
model file lowNMSSMTanBetaAtMZ has been added, where tan(beta) is
input at MZ.
FlexibleSUSY-1.1.1 [June, 08 2015]
* Bugfix (commit e1ea433): Catch NaNs from Slavich's NMSSM 2-loop
self-energies.
FlexibleSUSY-1.1.0 [May, 31 2015]
* Feature: Calculation of DR-bar weak mixing angle from Fermi
constant and Z pole mass. The implementation is based on
expressions from SOFTSUSY and works for the SM, MSSM, NMSSM and
their variants. The method for the calculation of the weak mixing
angle can be selected via the FSWeakMixingAngleInput variable in
the FlexibleSUSY model file.
Example:
FSWeakMixingAngleInput = FSFermiConstant; (* or FSMassW *)
Note: To achieve the maximum accuracy available, set the threshold
corrections loop order to 2 (FlexibleSUSY block entry 7)
* Feature: Support for non-SUSY models, renormalized in the MS-bar
scheme.
* Feature: 2-loop QCD corrections can be added when calculating the
top pole mass from the top DR-bar mass. These 2-loop contributions
can be enabled/disabled using entries 13 or 4 of the FlexibleSUSY
block in the SLHA input file.
* Feature: In the shipped FlexibleSUSY model files, the corresponding
default SARAH model file is specified. This allows a user to
create a new model with the simplified command:
./createmodel --name=CMSSM
The default SARAH model file to be used with a given FlexibleSUSY
model file can be set via FSDefaultSARAHModel = ;
* Feature: Complex model parameters are now supported.
* Feature: The CKM and PMNS matrix can now be used as low-energy
inputs. They are read from the VCKMIN and UPMNSIN input blocks,
respectively. Linked to this, the new model file CMSSMCKM was
added to demonstrate the input of the CKM matrix at low energies.
* Feature: Mark parameter points as invalid, for which the
calculation of one of the pole masses failed due to
non-convergence.
* Feature: New (non-templated) intermediate model class
_mass_eigenstates, which is able to calculate the pole and
running mass spectrum. _mass_eigenstates is derived from
_soft_parameters. The templated model class
is now derived from _mass_eigenstates .
* Bugfix (commit 6da2cbd, 8113e32a): ensure that the MSSM-like CP-odd
Higgs mass is used in the two-loop Higgs self-energies and
tadpoles. Before, there were cases where a Goldstone boson mass or
a singlet-like pseudoscalar mass was used.
* Bugfix (commit 29a0833): incorporate tadpole contributions in pole
masses of singlets
* Bugfix (commit c64a333): Softsusy's B1 function is now thread-save.
Before commit c64a333, the tau pole mass was varying due to a race
condition, if multi-threading is enabled and neither fflite nor
looptoos is used.
* Bugfix (commit d035544): Ignore trivial EWSB eqs. Makes the MRSSM
work in FlexibleSUSY with SARAH 4.5.x.
* Bugfix (commit d8a1521): The SM() preprocessor macro has been
renamed to LowEnergyConstant() in order to avoid collisions with
the copy constructor of the SM model class.
* Bugfix (commit 0c7a7ac): chop beta-function values smaller than the
zero-threshold to avoid failures of the RK integrator. The
zero-threshold is 1e-11 by default and can be changed via
Beta_function::set_zero_threshold() or entry 14 in the SLHA input
file.
* Bugfix (commit 29a1578): Ignore goldstone boson "pole mass"
tachyons.
FlexibleSUSY-1.0.4 [January, 15 2015]
* Add new user example program run_cmd_line_.x to run a
parameter point using command line parameters instead of an SLHA
input file.
* Allow input parameters in first guesses of scale definitions, for
example
SUSYScaleFirstGuess = Sqrt[Sqrt[LHInput[mq2[3,3]] * LHInput[mu2[3,3]]]]
* Adding support for FlexibleSUSY addons. They are placed inside the
addons/ directory and can be configued and compiled via
./configure --with-addons= && make
* Adding EWSB solvers using a fixed-point iteration (FPIRelative,
FPIAbsolute, FPITadpole). FPIRelative is now the first default
solver used. Thanks to Dylan Harries.
* Adding new NMSSM model file `NUTNMSSM' with non-universal soft
Higgs masses (EWSB output) and non-universal trilinear couplings
A_lambda and A_kappa at MX.
* Read user input W boson pole mass form SMINPUTS block entry 9.
* Read user input Z boson pole mass from SMINPUTS block entry 4.
* Automatic check for non-perturbative dimensionless model parameters
at the high-scale. The check can be disabled by stetting
FSCheckPerturbativityOfDimensionlessParameters = False;
in the model file. The threshold can be set via the
FSPerturbativityThreshold variable. The default threshold is
N[Sqrt[4 Pi]] = 3.54491.
* Check for tree-level tachyons at each scale (MZ and M_SUSY)
* Allow to force SLHA output for unphysical points (for example where
tachyons exist) in FlexibleSUSY block, entry 12.
* Bugfix (commit 6f7d3de): allow plain model parameters for scale
definition, for example in the form SUSYScale = vu .
* Bugfix (commit 44baa73): allow model parameters in first guesses of
scale definitions, for example
SUSYScaleFirstGuess = Sqrt[mq2[3,3] * mu2[3,3]]

of the self-energies with LowPrecision.
* Bugfix (commit fb0b906): Fix compilation with g++ 4.5.3.
