Abstract

The J/psi production in Pb-Pb interactions induced by 158 GeV/c incident Pb ions is studied as a function of centrality, as estimated from the neutral transverse energy or, alternatively, from the very forward hadronic energy of the collision. The J/psi yield exhibits a similar pattern with a first drop for mid-peripheral collisions and a steady decrease for the most central reactions. Conventional hadronic models are unable, to fairly reproduce this trend which finds a natural explanation in a deconfined quark-gluon phase scenario. The J/psi transverse momentum distributions and their dependence with centrality are also reviewed in this presentation.
