High-energy-physics event generation with PYTHIA 5.7 and JETSET 7.4
Description
Abstract Pythia and JETSET are the two main components of the “Lund Monte Carlo” program suite. They can be used to generate high-energy-physics “events”, i.e. sets of outgoing particles produced in the interactions between two incoming particles. Ideally these events should have the same average behaviour and the same fluctuations as real data. The underlying physics is not understood well enough to give an exact description; the programs therefore contain a combination of analytical results and vari... Title of program: PYTHIA 5.7 AND JETSET 7.4 Catalogue Id: ACTU_v1_0 Nature of problem High-energy collisions between elementary particles normally give rise to complex final states, with large multiplicities of hadrons, leptons, neutrinos and photons. The relation between these final states and the underlying physics description is not a simple one, for two main reasons. Firstly, we do not even in principle have a complete understanding of the physics. Secondly, any analytical approach is made untractable by the large multiplicities.
