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.

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.
Phys.Rev.Lett. 36 (1976) 1415, 1976.
Inspire Record 108462 DOI 10.17182/hepdata.21117

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)%.
