High-energy-physics event generation with Pythia 6.1

Abstract
Pythia version 6 represents a merger of the Pythia 5, Jetset 7 and SPythia programs, with many improvements. It can be used to generate high-energy-physics ‘events’, i.e. sets of outgoing particles produced in the interactions between two incoming particles. The objective is to provide as accurate as possible a representation of event properties in a wide range of reactions. The underlying physics is not understood well enough to give an exact description; the programs therefore contain a com...

Title of program: PYTHIA V6.154
Catalogue Id: ACTU_v2_0 [ADNN]

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 intractable by the large multiplicities.
