J/psi, psi' and Drell-Yan production in p p and p d interactions at 450-GeV/c.

The NA51 collaboration Abreu, M.C. ; Alessandro, B. ; Baldit, A. ; et al.
Phys.Lett.B 438 (1998) 35-40, 1998.
Inspire Record 481781 DOI 10.17182/hepdata.46539

J/ ψ and ψ ′ production cross-sections are measured in pp and pd collisions at 450 GeV/ c at the CERN-SPS. The Drell-Yan cross section for muon pairs in the mass range [4.3–8.0] GeV/ c 2 is also determined in the same experiment.

Measurement of the inclusive J / psi production cross-sections in anti-p p and p p collisions at s**(1/2) = 24.3-GeV

The UA6 collaboration Morel, C. ; Bernasconi, A. ; Breedon, R.E. ; et al.
Phys.Lett.B 252 (1990) 505-510, 1990.
Inspire Record 300180 DOI 10.17182/hepdata.29505

The inclusive cross section times branching ratio for J/ψ→e + e − has been measured in the forward region in the UA6 experiment for p p and pp collisions at √ s = 24.3 GeV. The ratio of the pp to p p cross sections is found to be 0.76 ± 0.14 ± 0.06. This demonstrates that gluon-gluon fusion dominates over quark-antiquark annihilation in the formation of the c c state.

Experimental J/psi Hadronic Production from 150-GeV/c to 280-GeV/c

The NA3 collaboration Badier, J. ; Boucrot, J. ; Bourotte, J. ; et al.
Z.Phys.C 20 (1983) 101, 1983.
Inspire Record 191240 DOI 10.17182/hepdata.2212

A detailed study ofJ/ψ hadronic production has been performed in a high statistics experiment (more than 1.5 106J/ψ observed in their dimuon decay mode). Data have been taken with incident π±,K±,p±, on hydrogen and platinum targets, at 150, 200 and 280 GeV/c. We find from the observed nuclear dependance of the cross sections, that about 18% of theJ/ψ are produced diffractively. Using known structure functions of the quarks in the nucleon and in the pion, we derive estimations for the gluon structure functions.

Measurement of Dimuon Production at the {ISR}

Antreasyan, D. ; Atwood, W. ; Battiston, R. ; et al.
Phys.Rev.Lett. 45 (1980) 863, 1980.
Inspire Record 153857 DOI 10.17182/hepdata.20656

Prompt dimuon production has been measured. Events with mass up to 25 GeV/c2 are observed, as well as the J and ϒ resonances. Cross sections are given for J and ϒ production. For the continuum, the scaling function F(τ) is measured at very small values of τ=ms covering the range 0.05<τ<0.20.
