PYTHIA
PYTHIA is a computer simulation program for particle collisions at very high energies (see event (particle physics)) in particle accelerators.[1]
History
PYTHIA was originally written in FORTRAN 77, until the 2007 release of PYTHIA 8.1 which was rewritten in C++.[1] Both the Fortran and C++ versions were maintained until 2012 because not all components had been merged into the 8.1 version.[1] However, the latest version already includes new features not available in the Fortran release.[2] Torbjörn Sjöstrand, Stefan Ask, Richard Corke, Stephen Mrenna, Stefan Prestel, and Peter Skands are the main contributors to PYTHIA.[3]
Features
The following is a list of some of the features PYTHIA is capable of simulating:[1]
- Hard and soft interactions
- Parton distributions
- Initial/final-state parton showers
- Multiparton interactions
- Fragmentation and decay
