Abstract
We discuss the use of quarkonium as a probe of hot and dense matter pr oduced in relativistic heavy ion collisions. We show that hard gluons present in the deconfined matter easily break up quarkonium states, wh ereas the softness of the gluon distributions in confined matter makes it almost transparent for slow J/psi's. An experimental test of these ideas using lead-hydrogen collisions at CERN-SPS is proposed.
