Abstract
The transverse-momentum and transverse-mass distributions of J/ψ mesons produced in proton-nucleus and lead-lead interactions at 400 GeV and 158 GeV/nucleon, respectively, were measured in the NA50 experiment. The change in these distributions with increasing centrality is studied for various interaction energies. Data obtained in the NA38 experiment for collisions of light nuclei at 200 GeV per nucleon is also used in the present analysis. Investigation of the transverse-momentum and transverse-mass distributions of J/ψ particles can provide additional information about the properties of the phase transition of ordinary nuclear matter to quark-gluon plasma.
