Centrality behaviour of J/$\psi$ production in NA50
The J/$\psi$ production in 158 A GeV Pb-Pb interactions is studied, in the dimuon decay channel, as a function of centrality, as measured with the electromagnetic or with the very forward calorimeters. After a first sharp variation at midcentrality, both patterns continue to fall down and exhibit a...

| description | The J/$\psi$ production in 158 A GeV Pb-Pb interactions is studied, in the dimuon decay channel, as a function of centrality, as measured with the electromagnetic or with the very forward calorimeters. After a first sharp variation at midcentrality, both patterns continue to fall down and exhibit a curvature change at high centrality values. This trend excludes any conventional hadronic model and is in agreement with a deconfined quark gluon phase scenario. We report also preliminary results on the measured charged multiplicity, as given by a dedicated detector. (17 refs). |
