The E771 collaboration Alexopoulos, T ; Antoniazzi, L ; Arenton, M ; et al.
Phys.Lett.B 374 (1996) 271-276, 1996.
Inspire Record 400873 DOI 10.17182/hepdata.42316

We report on the analysis of Charmonium and Bottomium states produced in p-Si interactions at s =38.7 GeV . The data have been collected with the open geometry spectrometer of the E771 Experiment at the FNAL High Intensity Lab. J ψ , ψ′ and γ total cross sections as well as the ratio B(ψ′ → μμ)σ(ψ′) (B( J ψ → μμ)σ( J ψ )) have been measured. Results are compared with theoretical predictions and with results at other energies.

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.

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.

J/psi Particle Production by 70-GeV/c Protons

Antipov, Yu.M. ; Bessubov, V.A. ; Budanov, N.P. ; et al.
Phys.Lett.B 60 (1976) 309, 1976.
Inspire Record 100281 DOI 10.17182/hepdata.6524

Invariant mass spectrum of μ + μ − pairs produced by 70 GeV/ c protons in Be target are presented. Distinct enhancements in the mass regions of ϱ, ω mesons, φ meson and J/ψ particle are observed. For J/ψ production x and p ⊥ 2 distributions are given. The total cross section for the reaction p + Be → ( J ψ → μ + μ − ) + … is equal to 9.5 ± 2.5 nb/nucleus .
