Abstract:
One of the striking features of particle production at high energies is the nearly equal abundance of matter and antimatter in the central rapidity region. In this work we present a study on particle yields at relativistic energies, including antiproton production. This study was carried out by updating the Chaos Many-Body Engine (CMBE) simulator[1-4}, based on flexibility and extensibility. There will be presented the new results obtained with CMBE, having new interactions and new disintegration channels introduced in the simulator. These results include experimental, and as well, CMBE and HIJING simulated distributions and standard ratios of particles produced in Cu-Cu collisions at RHIC-BNL energy.
