The Pythia program 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, with emphasis on those where strong interactions play a rôle, directly or indirectly, and therefore multihadronic final states are produced. The physics is then not understood well enough to give an exact description; instead the program has to be based on a combination of analytical results and various QCDbased models. This physics input is summarized here, for areas such as hard subprocesses, initial-and final-state parton showers, beam remnants and underlying events, fragmentation and decays, and much more. Furthermore, extensive information is provided on all program elements: subroutines and functions, switches and parameters, and particle and process data. This should allow the user to tailor the generation task to the topics of interest.

“…The GKS option is based on the GKS [Gut84] calculation, where some of the original mistakes in FKSS [Fab82] have been corrected. The GKS formulae have the advantage of giving the second-order corrections in closed analytic form, as not-too-long functions of x 1 , x 2 , and the y cut.…”

Event shape and charged particle inclusive distributions are measured using 750000 decays of the Z to hadrons from the DELPHI detector at LEP. These precise data allow a decisive confrontation with models of the hadronization process. Improved tunings of the JETSET, ARIADNE and HERWIG parton shower models and the JETSET matrix element model are obtained by tting the models to these DELPHI data as well as to identi ed particle distributions from all LEP experiments. The description of the data distributions by the models is critically reviewed with special importance attributed to identi ed particles.(To be submitted to Zeit. Phys. C) ii

“…For this purpose we generated events using the GKS [ 14] matrix element generator implemented in the JETSET 7.2 Monte Carlo program together with fragmentation parameters determined from a comparison of predicted and measured distributions for several event shape variables. Transition probabilities H o for a transformation of an event with jet multiplicityj on the parton level into an /-jet event after hadronization were evaluated.…”
