pythia
Lund Monte Carlo high-energy physics event generator
PYTHIA is a program for the generation of high-energy physics events, i.e. for the description of collisions at high energies between elementary particles such as e+, e-, p and pbar in various combinations. It contains theory and models for a number of physics aspects, including hard and soft interactions, parton distributions, initial- and final-state parton showers, multiple interactions, fragmentation and decay. It is largely based on original research, but also borrows many formulae and other knowledge from the literature.

- examples Install examples, usually source code
- fastjet Build jets using the sci-physics/fastjet package
- hepmc2 Adds support for High Energy Physics Monte Carlo Generators 2 sci-physics/hepmc
- +hepmc3 Adds support for High Energy Physics Monte Carlo Generators 3 sci-physics/hepmc
- highfive Support sci-libs/hdf5 and sci-libs/highfive
- lhapdf Support the use of external PDF sets via sci-physics/lhapdf
- mg5mes MadGraph matrix element plugins for parton showers
- mpich Multi-threading support via sys-cluster/mpich
- openmp Build support for the OpenMP (support parallel computing), requires >=sys-devel/gcc-4.2 built with USE="openmp"
- python Add optional support/bindings for the Python language
- rivet Support sci-physics/rivet
- root Use sci-physics/root trees and histograms (in examples only)
- static-libs Build static versions of dynamic libraries as well
- test Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
- zlib Add support for zlib compression
3 expansion flags (python targets, ABIs, cpu flags…)
