Production of $\psi$ (3100) and $\psi^{\prime}$ (3700) in p-Be Collisions at 400 GeV

Snyder, H.D. ; Hom, D.C. ; Lederman, L.M. ; et al.

We report preliminary results on the production of electron-positron pairs in the mass range 2.5 to 4 GeV in 400-GeV p-Be interactions. Production cross sections of the ψ(3100) near x=0 as a function of pt, x, and the decay angle are presented and implications of these new data for single direct leptons are discussed. A ψ′(3700) signal is observed at a level corresponding to σ(ψ′)σ(ψ)=(10±3)%.

Production of Positive Particles in 8-GeV/c pi- p and 18.5-GeV/c pi+- p Single-Particle Inclusive Reactions

Go, P.T. ; Shephard, W.D. ; Kenney, V.P. ; et al.
Phys.Rev.D 11 (1975) 3092, 1975.
Inspire Record 1941 DOI 10.17182/hepdata.4890

Inclusive cross sections and invariant single-particle distributions are presented for positive pions and protons produced in 8.05-GeV/c π−p and 18.5-GeV/c π±p inclusive reactions. Distributions in pT2 and in the longitudinal variables x, y (c.m.) and pl (lab) are shown. Comparisons are made with inclusive distributions for other particles produced in the same reactions.
