INCLUSIVE AND SEMIINCLUSIVE PRODUCTION OF POSITIVE PIONS AND PROTONS IN ANTI-P P INTERACTIONS AT 22.4-GEV/C

The ALMA ATA-DUBNA-HELSINKI-MOSCOW-PRAGUE-TBILISI collaboration Boos, E.G. ; Ermilova, D.I. ; Samoilov, V.V. ; et al.
Nucl.Phys.B 174 (1980) 45-67, 1980.
Inspire Record 159212 DOI 10.17182/hepdata.7929

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 · 10 4 inelastic p p 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.

rivet Analysis
Total Cross-Section for Hadron Production by e+ e- Annihilation at PETRA Energies

The JADE collaboration Bartel, W. ; Canzler, T. ; Cords, D. ; et al.
Phys.Lett.B 88 (1979) 171-176, 1979.
Inspire Record 142874 DOI 10.17182/hepdata.27277

The cross section for the process e + e − → multihadrons has been measured at the highest PETRA energies. We measure R (the total cross section in units of the point-like e + e - → μ + μ - cross section) to be 2.9 ± 0.7, 4.0 ± 0.5, 4.6 ± 0.4 and 4.2 ± 0.6 at s of 22, 27.7, 30 and 31.6 GeV, respectively. The observed average multiplicity, together with existing low energy data, indicate a rapid increase in multiplicity with increasing energy.

Charged Particle Multiplicity Distributions in p p Collisions at ISR Energies

The Aachen-CERN-Heidelberg-Munich collaboration Thome, W. ; Eggert, K. ; Giboni, K. ; et al.
Nucl.Phys.B 129 (1977) 365, 1977.
Inspire Record 120863 DOI 10.17182/hepdata.55890

We present the first direct measurements of charged-particle multiplicity distributions for pp collisions at ISR energies. The measurements are performed by means of a streamer chamber detector with large solid-angle coverage and excellent multitrack efficiency. Particle densities are observed to rise in the central region as s increases. The multiplicity distributions in this region deviate from a Poisson Law, thus giving evidence for correlations. These correlations are of the same type as those obtained from clustering of the collision products. The mean charged multiplicity over the full rapidity range increases faster than log s . Our data do not support an early onset of KNO multiplicity scaling.

Evidence for Dominant Vector Meson Production in Inelastic Proton Proton Collisions at 53-GeV Center-of-Mass Energy

Jancso, G. ; Albrow, M.G. ; Almehed, S. ; et al.
Nucl.Phys.B 124 (1977) 1-11, 1977.
Inspire Record 119346 DOI 10.17182/hepdata.35433

The Split Field Magnet facility at the CERN ISR has been used to measure inclusive resonance production in inelastic p-p collisions at a c.m. energy of 53 GeV. The mass spectrum of pairs of oppositely charged hadrons shows a strong correlation, which can be explained as a consequence of dominant vector meson production, accounting for more than 60% of all pions and kaons produced.
