A Monte Carlo program for generating hadronic final states

Abstract FIRST is a computer program to generate final state from high energy hadronic interactions using the Monte Carlo technique. It is based on a theoretical model in which the high degree of universality in such interactions is related with the existence of highly excited quark-antiquark bound states, called fire-strings. The program handles the decay of both fire-strings and unstable particles produced in the intermediate states. Title of program: FIRST Catalogue Id: ACBR_v1_0 Nature of problem Hadronic final states, originating from high energy collisions, show a high degree of universality in both physical composition and geometrical structure, thus suggesting a common underlying dynamics. A theoretical model, based on Quark-Geometro-Dynamics and Anisotropic-Chromo-Dynamics (QGD/ACD) and extensively developed in the last years is able to explain this relevant feature using highly excited quark-antiquark bound states (confined), called FireStrings (FS). The model assumes that the coll ...
