    "abstract": "Using the QGP motivated threshold model, where all the $J/\\psi$\u0027s are\nsuppressed above a threshold density, we have analyzed the preliminary PHENIX\ndata on the centrality dependence of nuclear modification factor for $J/\\psi$\u0027s\nin Cu+Cu and in Au+Au collisions, at RHIC energy, $\\sqrt{s}_{NN}$=200 GeV.\nCentrality dependence of $J/\\psi$ suppression in Au+Au collisions are well\nexplained in the model for threshold densities in ranges of 3.6-3.7 $fm^{-2}$.\n$J/\\psi$ suppression in Cu+Cu collisions on the other hand are not explained in\nthe model.",
