✦ Synopsis

The strong suppression of J/~ production recently observed in Pb-Pb collisions can be accounted for by a model which relates the suppression mechanism to the local energy density. In Pb-Pb collisions, the latter reaches values larger than in any other system studied previously.

Centrality dependence of J/ψ production in Au-Au collisions at √ s NN = 200 GeV is studied using the Glauber model plus the kinetic formation model. Initial J/ψ production and destruction by incoming nucleons are described by the Glauber model. J/ψ-charm equilibration in the gluon plasma is describe

Entropy production in the compression stage of heavy ion collisions is discussed within three distinct macroscopic models (i.e. generalized RHTA, geometrical overlap model and three-fluid hydrodynamics). We find that within these models ~80% or more of the experimentally observed final-state entropy
