Abstract

Results are presented on ρ + ω, (latin small letter o with stroke) and J/Ψ production in p-W and ³²S-W interactions at 200 GeV/c/nucleon measured via the dimuon decay in a large kinematic region. The data are normalized to the charged particle multiplicity in the same rapidity interval. They have been collected using the HELIOS/3 muon spectrometer at the CERN SPS. The ratio Bσ_{(latin small letter o with stroke)}/ (Bσ_ρ, + Bσ_ω), where B is the relevant resonance μμ branching fraction, increases between proton and sulphur projectiles, and is somewhat enhanced going from peripheral to central S-W interactions. This results from an increase in the number of produced (latin small letter o with stroke)'s per charged particle. The ratio is measured in different intervals of p_Τ and rapidity. It is not clearly dependent on p_Τ, but is larger at higher rapidities. J/Ψ production, likewise normalized to charged multiplicity, is significantly lower in S-W compared to p-W interactions.

N2 - Results are presented on ρ + ω, (latin small letter o with stroke) and J/Ψ production in p-W and 32S-W interactions at 200 GeV/c/nucleon measured via the dimuon decay in a large kinematic region. The data are normalized to the charged particle multiplicity in the same rapidity interval. They have been collected using the HELIOS/3 muon spectrometer at the CERN SPS. The ratio Bσ(latin small letter o with stroke)/ (Bσρ, + Bσω), where B is the relevant resonance μμ branching fraction, increases between proton and sulphur projectiles, and is somewhat enhanced going from peripheral to central S-W interactions. This results from an increase in the number of produced (latin small letter o with stroke)'s per charged particle. The ratio is measured in different intervals of pΤ and rapidity. It is not clearly dependent on pΤ, but is larger at higher rapidities. J/Ψ production, likewise normalized to charged multiplicity, is significantly lower in S-W compared to p-W interactions.
