pythia8-examples - 8.1.86-1.2 main

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.
