The NA50 Collaboration has measured heavy-quarkonium production in p-A collisions at 450 GeV incident energy (root s- = 29.1 GeV). We report here results on the production of the r states and of high-mass Drell-Yan muon pairs (m(mu mu) > 6 GeV/c(2)). The cross-section at midrapidity and the A-dependence of the measured yields are determined and compared with the results of other fixed-target experiments and with the available theoretical estimates. Finally, we also address some issues concerning the transverse momentum distributions of the measured dimuons. (c) 2006 Elsevier B.V. All rights reserved.

Abstract
The NA50 Collaboration has measured heavy-quarkonium production in p-A collisions at 450 GeV incident energy (root s- = 29.1 GeV). We report here results on the production of the r states and of high-mass Drell-Yan muon pairs (m(mu mu) > 6 GeV/c(2)). The cross-section at midrapidity and the A-dependence of the measured yields are determined and compared with the results of other fixed-target experiments and with the available theoretical estimates. Finally, we also address some issues concerning the transverse momentum distributions of the measured dimuons. (c) 2006 Elsevier B.V. All rights reserved.
