Abstract
Muon pairs produced in Pb-Pb interactions at 158 GeV/c per nucleon are used to study the transverse momentum distributions of the J/psi, psi' 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. (C) 2001 Published by Elsevier Science B.V.
