The cross section for J/~ production in Pb-Pb interactions at 158 GeV per nucleon is measured at the CERN SPS by the NA50 experiment. The final results from the 1995 run are presented here together with preliminary ones from the high-statistics 1996 run. An anomalous J/q1 suppression is observed in

✦ Synopsis
The strong "anomalous" J/~b suppression observed recently by the NA50 Collaboration at CERN SPS has attracted considerable attention. Is it the first signature of a longawaited quark-gluon plasma, or just a peculiar combination of "conventional" effects acting together to produce the puzzling pattern observed experimentally? This talk is an attempt to summarize the theoretical explanations proposed during the last two years.

Radial flow observed at AGS/SPS energies is very strong, with collective velo(:ities of matter reaching about 0.5c for central collisions of the heaviest ions. The lattice-based Equation of State (EOS) is however rather soft, due to the QCD phase transition. We show that both statements are consiste
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.
