Abstract

Cross sections for J/psi<,psi>' and Drell-Yan production in Pb+Pb collisions at 158xA GeV/c are presented and compared with results obtained by the NA38 and NA51 collaborations. The Pb+Pb data have been collected by the NA50 collaboration using the NA38 dimuon spectrometer. The Drell-Yan mechanism is found to scale as (A(projectile). B-target) in p+B-target and A(projectile)+B-target collisions including Pb+Pb collisions. Regarding J/psi, an anomalous suppression is observed in Pb+Pb collisions with respect to the suppression observed in p+B-target, O+B-target and S+U collisions. The cross section ratios psi'/(J/psi) are similar in Pb+Pb and S+U collisions.
