Charged particle multiplicities in nuclear collisions at 200-GeV/N

The NA35 collaboration Bächler, J. ; Bartke, J. ; Bialkowska, H. ; et al.
Z.Phys.C 51 (1991) 157-162, 1991.
Inspire Record 320907 DOI 10.17182/hepdata.14983

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.

Negative Pion Production in Proton Proton Interactions at 69-GeV/c

The French-Soviet collaboration Bumazhnov, V.A. ; Ermolov, P.F. ; Fenyuk, A.S. ; et al.
Phys.Lett.B 50 (1974) 283-286, 1974.
Inspire Record 89197 DOI 10.17182/hepdata.27949

Inclusive spectra of π − production for pp interactions are discussed at 69 GeV/ c both in the central and in the fragmentation region and are compared to data at lower and higher energies. The p T dependence of the invariant structure function is also analysed.

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.
