Xi- and Anti-xi+ Production in $\pi^- p$ Interactions at 16-{GeV}/$c$

Balea, E. ; Berceanu, S. ; Coca, C. ; et al.
Nucl.Phys.B 150 (1979) 345-356, 1979.
Inspire Record 131824 DOI 10.17182/hepdata.34790

Production of Ξ − and Ξ + hyperons has been studied in 16 GeV/ c π − p interactions. Cross sections are given for Ξ − and gX + production. Distributions and average values of c.m. production angle, transverse and longitudinal variables are presented. Characteristics of some Ξ final states identified are also presented.

Single Particle Inclusive Spectra of Charged Particles in anti-p p Interactions at 22.4-GeV/c

The Alma Ata-Dubna-Helsinki-Kosice-Moscow-Prague collaboration Boos, E.G. ; Samoilov, V.V. ; Takibaev, Zh.S. ; et al.
Nucl.Phys.B 121 (1977) 381-392, 1977.

The inclusive spectra for p p collisions at 22.4 GeV/ c are investigated. We show that the transverse momentum distributions resemble those in high-energy pp interactions and discuss the influence of annihilation processes on the p T 2 distributions. The invariant inclusive cross section for pions in the central region is found to be 28 ± 1 mb. A charge asymmetry is indicated by the y ∗ spectrum in the central region, the asymmetry parameter having the value 0.15 ± 0.01. Finally, we estimate the upper limit of the diffraction dissociation of the beam particle to be 3.68 −0.15 +0.45 mb.

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 .
