Transverse momentum dependence of charmonium suppression in Pb-Pb collisions at the CERN SPS

Charmonium suppression in Pb-Pb collisions at 158 GeV/c per nucleon is investigated in detail with the study of the transverse momentum distributions of J/ psi as a function of the centrality of the collision. It is shown that the observed J/ psi suppression in Pb-Pb interactions is particularly sig...

description Charmonium suppression in Pb-Pb collisions at 158 GeV/c per nucleon is investigated in detail with the study of the transverse momentum distributions of J/ psi as a function of the centrality of the collision. It is shown that the observed J/ psi suppression in Pb-Pb interactions is particularly significant mainly at low transverse momentum where it strongly depends on centrality. For peripheral Pb- Pb collisions, the transverse momentum dependence of the J/ psi cross section is, as a function of centrality, qualitatively similar to the dependence observed in p-A and S-U collisions. Comparing peripheral and central Pb-Pb collisions, the data show a relative suppression in the whole p/sub T/ range although its amplitude significantly decreases with increasing p/sub T/ and becomes almost p/sub T/ independent for the highest p/sub T/ values.
