A Measurement of $J / \psi$ and $\psi^{\prime}$ Production in 300-GeV/c Proton, Antiproton and $\pi^{\pm}$ Nucleon Interactions

The E705 collaboration Antoniazzi, L. ; Arenton, M. ; Cao, Z. ; et al.
Phys.Rev.D 46 (1992) 4828-4835, 1992.
Inspire Record 338055 DOI 10.17182/hepdata.22667

Hadroproduction of the Jψ and ψ′ states has been studied in 300-GeV/c proton, antiproton, and π±Li interactions. Both total and differential cross sections in xF and pT have been measured for the Jψ for the π±, proton, and antiproton interactions. The ratio of ψ′ to Jψ production has been determined for the four types of beam particles.

A Measurement of Elastic $J / \psi$ Photoproduction Cross Section at Fermilab E687

The E687 collaboration Frabetti, P.L. ; Paolone, V.S. ; Yager, P.M. ; et al.
Phys.Lett.B 316 (1993) 197-206, 1993.
Inspire Record 359356 DOI 10.17182/hepdata.28834

Measurements of elastic photoproduction cross sections for the J / ψ meson from 100 GeV to 375 GeV are presented. The results indicate that the cross section increases slowly in this range. The shape of the energy dependence agrees well with the photon-gluon fusion model prediction.
