| 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. |
