J/$\psi$ Measurements in $\sqrt{s_{NN}}$=200 GeV Au+Au Collisions

ORAL

Abstract

Heavy quarkonia production is considered to be one of the most important probes of the hot and dense state created in relativistic heavy ion collisions. At RHIC energy, J/$\psi$ yields, especially the large feed-down contributions from $\chi_c$ and $\psi'$ states, are expected to be suppressed in a quark gluon plasma due to color screening. The PHENIX experiment at RHIC has measured J/$\psi$ production in $\sqrt{s_{NN}}$=200 GeV Au+Au collisions at both forward ($1.2<|y|<2.2$) and mid ($|y|<0.35$) rapidities. The most recent results for the centrality, rapidity and transverse momentum dependence of J/$\psi$ production will be discussed and compared with PHENIX baseline measurements and various theoretical calculations.
