MEVSIM: A Monte Carlo Event Generator for STAR

A fast, simple to use Monte Carlo based event generator is presented which is intended to facilitate simulation studies and the development of analysis software for the Solenoidal Tracker at RHIC (Relativistic Heavy Ion Collider) (STAR) experiment at the Brookhaven National Laboratory (BNL). This new event generator provides a fast, convenient means for producing large numbers of uncorrelated A+A collision events which can be used for a variety of applications in STAR, including quality assurance evaluation of event reconstruction software, determination of detector acceptances and tracking efficiencies, physics analysis of event-by-event global variables, studies of strange, rare and exotic particle reconstruction, and so on. The user may select the number of events, the particle types, the multiplicities, the one-body momentum space distributions and the detector acceptance ranges. The various algorithms used in the code and its capabilities are explained. Additional user information is also discussed. The computer code implementation is called mevsim.
