Results are presented on the charge exchange reaction$\bar pp \to \bar nn$ and$\bar np$ annihilations from bubble chamber exposures to antiproton beam of momenta 700 and 760 MeV/c. The differential cross section of$\bar pp \to \bar nn$ shows a forward spike followed by a clear dip bump structure. Total annihilation cross section of$\bar np$ for average$\bar n$ momentum of 700 MeV/c has been evaluated to be 55.4±2.2 mb. The multiplicity, Feynmanx andpT2 distributions for inclusive charged pions in$\bar pp$ and$\bar np$ annihilations are found to be similar. The emission of charged pions from$\bar np$ annihilations are found to be consistent with thermodynamic models with temperature ∼110 MeV.

The intermediate and forward gamma detectors of EHS are used to reconstructπ°'s produced by 360 GeV/cpp interactions in the Rapid Cycling Bubble Chamber (RCBC). Using thepp forwardbackward symmetry, the inclusiveπ° production cross section is obtainedσπ°=(132±11) mb. The averageπ° multiplicity is determined as a function of the charged particle multiplicity. The (1−x) dependence is given for differentpT regions.

$\rho^0$ Production in $\pi^- p$ Interactions at 100-{GeV}/$c$, 200-{GeV}/$c$ and 360-{GeV}/$c$

Higgins, P.D. ; Shephard, W.D. ; Biswas, N.N. ; et al.

Phys.Rev.D 19 (1979) 65, 1979.

Inspire Record 7275 DOI 10.17182/hepdata.4591

Inclusive and semi-inclusive cross sections for gp0 production in 100, 200, and 360 GeV/c π−p interactions are presented. Differential cross sections for ρ0 production as functions of c.m. rapidity and transverse momentum are compared with the corresponding differential cross sections for pion production. Effects of various methods of estimating background on the values obtained for ρ0 production cross sections are discussed. About 10% of the final-state charged pions appear to come from ρ0 decay. Thus, while ρ0 production and decay is a significant source of final-state pions, other sources must contribute the majority of the produced pions.

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.

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 .
