Phi, rho, and omega production in p U, O U and S U reactions at 200-GeV per nucleon

The NA38 collaboration Baglin, C. ; Baldisseri, A. ; Bussiere, A. ; et al.
Phys.Lett.B 272 (1991) 449-454, 1991.
Inspire Record 325656 DOI 10.17182/hepdata.29289

Low mass muon pair production at high P T and low X F studied in pU, OU and SU 200 GeV per nucleon react ions. When energy density or projectile mass are increased, φ production is enhanced as compared with the yield of muon pairs in the mass continuum (1.7< M μμ < 2.4 GeV/ c 2 ), whereas the production of ω and ϱ, experimentally unresolved, remains approximately constant. This φ enhancement is in agreement with predictions based on quark-gluon plasma formation and, together with the previously reported J/Ψ suppression, puts severe constraints on a purely hadronic description of nucleus-nucleus collisions.

Muon pair and vector meson cross-sections in p W and S U collisions at 200-GeV/nucleon

The NA38 collaboration Abreu, M.C. ; Baglin, C. ; Baldisseri, A. ; et al.
Phys.Lett.B 368 (1996) 230-238, 1996.
Inspire Record 428066 DOI 10.17182/hepdata.28422

Muon pair production is studied in p - W and S  U collisions at 200 GeV per nucleon, as a function of transverse momentum P Tμμ . The inclusive ϱ + ω and Φ differential cross-sections dσ dP T are measured in the dimuon decay channel, for P T ≥ 0.6 GeV/c, in the central rapidity region, 3.0≤ y ≤ 4.0. Assuming the power law A-dependence σ = σ 0 ( A beam · A target ) α , the study of the integrated cross-sections for p - W and S  U collisions leads to α ϱ + ω = 1.00±0.02±0.07 and α Φ = 1.23±0.03±0.05, showing clear evidence of Φ enhancement in S  U interactions as compared to p - W collisions.

Inclusive mu - Pair Production at 150-GeV by pi+ Mesons and Protons

Anderson, K.J. ; Henry, G.G. ; McDonald, K.T. ; et al.
Phys.Rev.Lett. 37 (1976) 799, 1976.
Inspire Record 3993 DOI 10.17182/hepdata.21035

We report the measurements of the inclusive μ-pair production by 150-GeV protons and π+ mesons on beryllium. Absolute cross sections as well as the Feynman-x and PT dependence are presented in the mass region between 0.211 and 3.5 GeV/c2. Upper limits are also given for the inclusive production of η and ρ′(1600) mesons.
