Abstract

Using the QGP motivated threshold model, where all the J/ψ's are suppressed above a threshold density, we have analyzed the preliminary PHENIX data on the centrality dependence of nuclear modification factor for J/ψ's in Cu+Cu and in Au+Au collisions, at RHIC energy, sNN=200 GeV. Centrality dependence of J/ψ suppression in Au+Au collisions are well explained in the model for threshold densities in ranges of 3.6-3.7 fm-2. J/ψ suppression in Cu+Cu collisions on the other hand are not explained in the model.
