A Monte Carlo generator for high energy nucleus-nucleus collision

A Monte Carlo simulator is presented to reproduce data of nucleus-nucleus i nteractions at high energies. The program is designed in a microscopic poin t of view, where the cascade approach is applied. Moreover, each nucleon fr om both the target and the projectile is followed up on the time scale alon g the collision time. The effect of the mean field that depends on the nucl ear density is considered. Elastic and inelastic scattering are allowed for the nucleon binary collisions during the cascade according to their center of mass energies. Particle productions are studied through the fragmentati on of strings and sub-strings, which may be formed due to the color field b etween the interacting quarks rather than the interactions among gluons. Th e predictions of the Monte Carlo are fairly compared with the recent CERN d ata of p-S-32 and S-32-S-32 collisions at 200 A GeV incident energy.
