Single-particle inclusive spectra of charged particles in $\text{p}\text{p}$ interactions at 22.4 GeV/c

Abstract

The inclusive spectra for $\text{p}\text{p}$ collisions at 22.4 GeV/c are investigated. We show that the transverse momentum distributions resemble those in high-energy pp interactions and discuss the influence of annihilation processes on the p_T² distributions. The invariant inclusive cross section for pions in the central region is found to be 28 ± 1 mb. A charge asymmetry is indicated by the $\text{y}{}^{\mathrm{\ast }}$ spectrum in the central region, the asymmetry parameter having the value 0.15 ± 0.01. Finally, we estimate the upper limit of the diffraction dissociation of the beam particle to be 3.68_−0.15^+0.45 mb.
