$J/\Psi$ production in $Cu+Cu$ and $Au+Au$ collisions measured by PHENIX at RHIC

Abstract

PHENIX preliminary results on the $J/\Psi$ production in $Cu+Cu$ and $Au+Au$ collisions at $\sqrt{s_{NN}}=200$ GeV are presented. They are compared to results from lower energy experiments NA50 and NA60 at CERN SPS and to expectations from various theoretical models.
