Chu, M -

We present a simple phenomenological model of J/psi suppression in ultra-relativistic heavy-ion collisions, which gives good agreement with the recent CERN NA38 data on 200 GeV/A Oxygen-Uranium collisions. The essential ingredients of our model are the existence of a characteristic energy density epsilon/sub s/ above which no J/psi could be formed, and Bjorken's longitudinal scaling hydrodynamics. With these assumptions, we deduce a lower bound on epsilon/sub s/ from the NA38 data: epsilon/sub s/greater than or equal to1 GeV/fm/sup 3/. Fixing parameters from the Oxygen data, we also make predictions for 200 GeV/A Sulphur-Uranium interactions.
