# Pythia Event Generator

## Purpose

Provides expert guidance on Pythia event generation for high-energy physics, including process configuration, hadronization, and shower matching.

## Capabilities

- Process selection and configuration
- Parton distribution function management
- Hadronization and decay settings
- Underlying event tuning
- HepMC output generation
- Shower matching (MLM, CKKW)

## Usage Guidelines

1. **Process Configuration**: Select physics processes for event generation
2. **PDFs**: Configure parton distribution functions
3. **Hadronization**: Set hadronization and decay parameters
4. **Tuning**: Apply appropriate underlying event tunes
5. **Output**: Generate HepMC format for downstream analysis
