ABSTRACT: The dimuon production in 200 GeV/nucleon oxygen-uranium interactions is studied by the NA 38 Collaboration. The production ofJ/, correlated with the transverse energyET, is investigated and compared to the continuum, as a function of the dimuon massM and transverse momentumPT. A value of 0.640.06 is found for the ratio (/Continuum at highET)/(/Continuum at lowET), from which theJ/ relative suppression can be extracted. This suppression is enhanced at lowPT.

ABSTRACT: The like-sign dimuons copiously recorded in the NA 38 experiment both inp-U and O–U reactions at 200 GeV/nucleon are interpreted as resulting from decays of andK mesons in comparable proportions. The ++/–– ratio is large (1.7) and ascribed to theK
+ being more copiously produced than theK
–. Both the average transverse momentum and the ++/–– ratio are comparable forp-U and O–U reactions, and both increase only slightly with the transverse energyE

ABSTRACT: Muon-pair production has been measured in pCu, pU, OCu, OU and SU collisions at 200 GeV per nucleon. The cross sections are compatible with the atomic number dependence (Aproj.Atarg.)α where α=0.91±0.04 for the J/ψ resonance and α=1.01±0.04 for muon pairs produced in the mass continuum between 1.7 and 2.7 GeV/c2.

ABSTRACT: The dimuon production in 200 GeV/nucleon O-U, O-Cu, S-U and p-U reactions is studied in function of transverse energy ET produced by the collision. The J/ψ production relative to continuum events is suppressed for heavy ion induced reactions when ET increases. This suppression is enhanced at low transverse momentum. The π and K meson distributions extracted from the data, have, for each reaction, a similar average transverse momentum which increases only slightly with the transverse energy.
