Title: Measurements of J/{psi} yield at forward-rapidity and mid-rapidity in Au+Au collisions at {radical}(S{sub NN}) = 200 GeV by PHENIX at RHIC

Abstract

Results on the charm quarkonia production in {radical}(S{sub NN}) = 200 GeV Au+Au collisions at the Relativistic Heavy Ion Collider (RHIC) are presented. The J/{psi} yield was measured at the PHENIX experiment via the {mu}+{mu}- decay channel at forward-rapidity and via the e+e- channel at mid-rapidity. The nuclear modification factor and the mean square of the transverse momentum of J{psi} at forward-rapidity and mid-rapidity are shown as a function of collision centrality and compared to theoretical calculations.
