Multiplicity of Secondary Particles in Inelastic Proton - Neon Interactions at 300-{GeV}/$c$

The data on the total inelastic and partial cross sections in pNe interactions at 300 GeV are presented. It is found that the total cross section, σin(pNe)=356±13 mb, and multiplicity distributions of the number of negative and relativistic charged particles are in good agreement with predictions of a multiple-scattering model based on Glauber's approach. The multiplicity of negative particles obeys the Koba-Nielsen-Olesen (KNO) scaling, but it is observed that the KNO function depends on the atomic mass number of the target. From an analysis of the average multiplicities of secondary particles, it is shown that approximately 10 percent of the fast (p≳1.2 GeV) positive secondaries are protons, which are derived from the nucleons in the neon nucleus.

Production of Slow Protons in the Inclusive Reactions p (pi+) n --> p (Slow) x at 195-GeV/c

Eisenberg, Y. ; Haber, B. ; Hochman, D. ; et al.

Inspire Record 121977 DOI 10.17182/hepdata.35148

The inclusive reactions pn → p s + x and π + n → p s + x at incident momentum of 195 GeV/ c have been studied in an exposure of the Fermilab 30 inch deuterium filled bubble chamber to a mixed ( π + , p) beam. Analysing the t and M 2 dependence of our data within the framework of triple-Regge models we conclude that pion exchange yields a dominating contribution. Comparing our data with the pp results we conclude that isoscalar Regge exchange, ω, is much larger than isovector, ϱ, Regge exchange. We observe significant leading π − emission from the recoiling mass x, comparable to that observed in on-mass-shell π − p → π − experiments. This verifies our conclusions about pion-exchange dominance in the above reactions.

The Inclusive Reactions $p + n \to p + X$ and $\pi^+ + n \to p + X$ at 100-GeV/c

Hanlon, J. ; Brody, A. ; Engelmann, R. ; et al.
Phys.Rev.Lett. 37 (1976) 967, 1976.
Inspire Record 108156 DOI 10.17182/hepdata.21040

We have measured the inclusive cross section for the reactions p+n→p+X and π++n→p+X at 100 GeV/c in the kinematic region |t|<1.0 GeV2. The data were obtained from an exposure of the Fermilab 30-in. deuterium-filled bubble chamber to a tagged positively charged beam. The differential cross sections for these reactions are observed to scale in the ratio of the pn and π+n total cross sections and to be consistent with the predictions of a Reggeized one-pion-exchange model.
