Abstract	In the past few years the NA50 experiment carried out a comprehensi v e study of heavy quarkonia production, both in proton-nucleus and nucleus-nucleus collisions. In particular , data from p-A collisions hav e been collected in order to estimate the size of the absorption of quarkonia states in cold nuclear matter . Along with the studies on J/ ψ and ψ , NA50 measured for the first time ϒ production at 450 GeV incident energy ( s 29 1 GeV) on fi v e 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 ϒ and Drell-Yan production. We analyzed as well the transverse momentum and rapidity distributions for the ϒ meson. The results are compared with previous measurements and with the predictions of theoretical models.
