PHENIX results for J/ψ transverse momentum and rapidity dependence in Au+Au and Cu+Cu collisions

The PHENIX experiment at RHIC has measured J/ψ production in √sNN=200 GeV Au+Au and Cu+Cu collisions at forward (1.2 < |y| < 2.2) and mid (|y| < 0.35) rapidities. The most recent results for the rapidity and transverse momentum dependence of J/ψ production are presented and compared with PHENIX baseline p + p measurements and selected theoretical calculations. We find that the J/ψ production is significantly more suppressed, as compared to p + p, at forward rapidity than at mid rapidity in central Au+Au collisions
