Data on multiplicities of charged particles produced in proton-nucleus and nucleus-nucleus collisions at 200 GeV per nucleon are presented. It is shown that the mean multiplicity of negative particles is proportional to the mean number of nucleons participating in the collision both for nucleus-nucleus and proton-nucleus collisions. The apparent consistency of pion multiplicity data with the assumption of an incoherent superposition of nucleon-nucleon collisions is critically discussed.

Topological Cross-sections and Charged Particle Multiplicities in $p p$ Interactions at 360-{GeV}/$c$

The EHS-RCBC collaboration Bailly, J.L. ; Banerjee, S. ; Bartl, W. ; et al.
Z.Phys.C 23 (1984) 205, 1984.
Inspire Record 195218 DOI 10.17182/hepdata.2141

Using data obtained with EHS equipped with the Rapid Cycling Bubble Chamber (RCBC) exposed to a proton beam of 360 GeV/c, we calculate topological cross sections. We present in great detail the procedure and the techniques used to correct raw data. Finally, we give multiplicity moments and multiplicity correlations and we compare the values obtained in our experiment, together with data at other energies, with different models.

Interactions of 200-GeV/c protons and antiprotons on hydrogen, argon, and xenon targets were studied with a streamer-chamber vertex spectrometer at the CERN SPS. Results on multiplicities, rapidity distributions, and correlations are presented and compared with predictions of current models.

CHARGED AND NEUTRAL PARTICLE PRODUCTION FROM 400-GEV/C P P COLLISIONS

Kass, R.D. ; Ko, W. ; Lander, R.L. ; et al.
Phys.Rev.D 20 (1979) 605-614, 1979.
Inspire Record 146628 DOI 10.17182/hepdata.24207

Charged- and neutral-particle production from 400-GeV/c pp collisions are measured simultaneously using the Fermilab 15-ft bubble chamber. The π0 and K0 cross sections are rising at Fermilab energies, while the Λ0 cross section remains fairly constant. Similarly, the average number of π0's and K0's increases as a function of the number of negative particles in an event, yet no such dependence is noted for the Λ0's. The ratio of average number of π0 to average number of π− per inelastic collisions is found to be constant at Serpukhov and Fermilab energies (40 to 400 GeV/c) and equal to 1.22±0.02. Cross sections for Σ0 and Σ¯0 production are measured and limits are found for η0 and ω0 production. Neutral- and charged-pion correlations are compared with five pion-production models.

Multiplicities, topological cross-sections, and single particle inclusive distributions from p p interactions at 12-GeV/c and 24-GeV/c

The Bonn-Hamburg-Munich collaboration Blobel, V. ; Brandenburg, G.W. ; Fesefeldt, H. ; et al.
Nucl.Phys.B 69 (1974) 454-492, 1974.
Inspire Record 94379 DOI 10.17182/hepdata.32358

Results on multiplicities, topological cross sections, total particle production cross sections, and correlations between charged particle and π 0 production are presented for pp interactions at 12 and 24 GeV/ c incident laboratory momentum. Inclusive production of π ± , K s 0 , p , Λ, Σ ± and Λ is studied; particle spectra are shown in single and double differential form and are compared, in different kinematic regions, with data obtained at other incident momenta and with other beam particles.

A Comparison of Hadron Production in $p \bar{p}$ and $p p$ Collisions in the Central Region at $\sqrt{s}=53$-{GeV}

The Axial Field Spectrometer collaboration Akesson, T. ; Albrow, M.G. ; Almehed, S. ; et al.
Nucl.Phys.B 228 (1983) 409-423, 1983.
Inspire Record 190653 DOI 10.17182/hepdata.37131

We have studied the inclusive production of the hadrons π ± , K ± , p, p , Λ, Λ , ρ and ⋉ in the central region at the ISR s = 53 GeV , in both pp and p p collisions. Differences are observed only for K ± , p, and p production. We then study also correlations between low- p T pp and p p pairs in the two types of collisions, separating the contribution from baryon pair production and from the incident particles (stopping protons). We observe a positive correlation between two stopping protons; between the production of two pairs, and between a stopping proton and a pair production, there are negative correlations.

Comparison of Inclusive Distributions in $p p$ and $\bar{p} p$ Interactions at $\sqrt{s}=53$-{GeV}

Phys.Lett.B 132 (1983) 458-462, 1983.
Inspire Record 191414 DOI 10.17182/hepdata.30631

Measurements are presented of inclusive distributions in pp and p p interactions at √ s = 53 GeV. The data were obtained at the CERN ISR using the Split Field Magnet spectrometer with a minimum bias trigger. The inclusive distributions are analyzed as functions of the transverse momentum, the rapidity and the Feynman- x variable.
