Abstract Inclusive ϱ 0 production has been investigated in p p reactions at 22.4 GeV/ c . The total cross section for ϱ 0 production is 8.1 ± 2.0 mb. The average ϱ 0 s per event is 0.17 ± 0.03. The average transverse momentum, as obtained by extrapolation of a fitted simple exponential to the p T 2 distribution, is 0.52 ± 0.12 GeV/ c . The Feynman x and c.m. rapidity distributions show ϱ 0 to be “centrally” produced.

Abstract The connection between particle production in antiproton-proton annihilation and non-diffractive proton-proton processes is discussed in the framework of the dual unitarization scheme. We calculate relative multiplicity moments for antiproton-proton annihilation using the moments of non-diffractive proton-proton interactions and find good agreement with experimental annihilation data.

Kuratashvili; T. P. Topuriya; V. D. Tsintsadze

The Bose-Einstein interference effect is studied using 7333 events of ¯pp-interactions withnch≧6 at 22·4 GeV/c. An essential dependence of the strength of this effect on the pion pair velocity is observed. An indication is obtained that processes with essentially different time characteristics (τ<1 fm and τ>2 fm) contribute to ¯pp-interactions at 22·4 GeV/c. The interpretation based on abundant resonance production in high energy collisions is discussed.

Abstract The inclusive and semi-inclusive production of Δ ++ (1236) is investigated in p p interactions at 22.4 GeV/ c . The Δ ++ cross section is 1.78 ± 0.18 mb in the region of | t p Δ | ⩽ 0.74 (GeV/ c ) 2 . The differential cross section has been studied as a function of transverse and longitudinal variables. Evidence for the one-pion exchange contribution to the Δ ++ inclusive process has been obtained from the decay angular distributions of the Δ ++ .

p interactions with the leading particle and the slow proton subtracted are used as data on soft processes. Considerable similarity between them and hard processes, such ase+e− annihilation into hadrons, is found by means of studying charged multiplicities, KNO scaling and longitudinal as well as transverse spectra.

New results on the inclusive and semi-inclusive production of π+ mesons and protons in the whole phase space are given for about 2.2 · 104 inelastic pp interactions at 22.4 GeV/c. A method of statistical separation for spectra of particles of the same charge which are produced in CP-symmetrical reactions is discussed in detail. Experimental data are compared with quark-parton model predictions.
