【 摘 要 】

RHIC is a versatile machine which has the unique capability to collide different nuclei. One new system recently explored is that of Cu on Au at 200 GeV. One of the first PHENIX measurements made in these collisions was that of forward and backward J/ψ production, where the production mechanism for J/ψ is believed to be dominated by gluon-fusion interactions. Resultant yields from such interactions can be modified in both cold and hot nuclear matter, where the asymmetric nature of the initial state of this collision system may give rise to a systematic difference in forward and backward particle production. In these proceedings, we present our latest studies and compare the resulting distributions to those from earlier heavy-ion collision systems.
