“…However, Bowler [Bow81] has shown, within the framework of the Artru-Mennessier model [Art74], that a massive endpoint quark with mass m Q leads to a modification of the symmetric fragmentation function, due to the fact that the string area swept out is reduced for massive endpoint quarks, compared with massless ditto. The Artru-Mennessier model in principle only applies for clusters with a continuous mass spectrum, and does not allow an a term (i.e.…”

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 hadronization effects induced by various color connections of the four-quark system in e + e − annihilation are briefly reviewed. A special color connection of the four-heavy-quark system with no color separation favors the production of doubly heavy baryons. For the related three-jet case, the corresponding hadronization has not yet been considered. We argue that it can be effectively described as two-string fragmentation in addition to the leading heavy diquark fragmentation. The production rate and the properties of the final-state hadron systems are discussed. Emphasis is placed on the string effect as a fingerprint of this hadronization procedure.
