The mean squared transverse momentum of J/ψ's measured in p Cu, p U, O Cu, O U
and S U collisions at 200 GeV/nucleon is analyzed in terms of initial state interactions …

Data on J/ψ production in inelastic proton-proton, proton-nucleus, and nucleus-nucleus
interactions at 1 5 8 A GeV are analyzed and it is shown that the ratio of mean multiplicities …

The study of the J ψ transverse momentum distribution in oxygen-uranium reactions at 200
GeV/nucleon shows that〈 PT〉 and〈 PT2〉 increase with the transverse energy of the …

Muon-pair production has been measured in p Cu, p U, O Cu, O U and S U
collisions at 200 GeV per nucleon. The cross sections are compatible with the atomic …

The NA50 collaboration has measured the J/¢ production in Pb-Pb collisions at 158 GeV/c
per nucleon [5]. An" anomalous" suppression of the J/¢ production cross section was …

The momentum diffusion effect of the quark pair due to the multiple scattering in a nuclear
medium is studied to explain the observed J/ψ yields in SPS experiments. The resulting …

The experimental ratio of ψ′ to J/ψ is approximately a constant in pA collisions, but
decreases as the transverse energy increases in nucleus-nucleus collisions. These peculiar …

The NA50 Collaboration has recently observed that the J/ψ production rate in Pb-Pb
collisions decreases more rapidly as a function of the transverse energy for the most central …
