J/Psi suppressions in a thermally equilibrating quark-gluon plasma at RHIC

Abstract

We estimate the survival probability of $J/\psi$ in relativistic heavy-ion collisions, using both short-distance QCD and nuclear absorption mechanism. The suppression is found to be almost 100 percent for a thermally equilibrating quark-gluon plasma. The measurement of such a huge suppression of $J/\psi$ may suggest the existence of a deconfined partonic medium, possibly a thermalised quark-gluon plasma, at RHIC.
