Muon pairs produced in Pb–Pb interactions at 158 GeV/ c per nucleon are used to study the transverse momentum distributions of the J/ ψ , ψ ′ and dimuons in the mass continuum. In particular, the dependence of these distributions on the centrality of the Pb–Pb collision is investigated in detail.

Bottomonium and Drell-Yan production in p-A collisions at 450 GeV

The NA50 collaboration Alessandro, B. ; Alexa, C. ; Arnaldi, R. ; et al.

The NA50 Collaboration has measured heavy-quarkonium production in p-A collisions at 450 GeV incident energy (sqrt(s) = 29.1 GeV). We report here results on the production of the Upsilon states and of high-mass Drell-Yan muon pairs (m > 6 GeV). 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.

Table 2

Mean pT and Mean PT**2 for Drell-Yann (4.5<MMUMU<8 GeV/c**2) Errors for Drell-Yann are purely statistical, error value for Upsilon includes a systematical error due to uncertianty in the extrapolation of the drell-yann yield into the upsilon region. The total error is anyway dominated by the statistical contribution.
