Abstract

In the past few years the NA50 experiment carried out a comprehensive study of heavy quarkonia production, both in proton-nucleus and nucleus-nucleus collisions. In particular, data from p-A collisions have been collected in order to estimate the size of the absorption of quarkonia states in cold nuclear matter. Along with the studies on J/psi and psi', NA50 measured for the first time Y production at 450 GeV incident energy ( sqrt(s)=29.1 GeV) on five nuclear targets (Be, Al, Cu, Ag and W) in the dimuon decay channel. We report here results on the cross section at mid-rapidity and the nuclear dependence of Y and Drell-Yan production. We analyzed as well the transverse momentum and rapidity distributions for the Y meson. The results are compared with previous measurements and with the predictions of theoretical models.
