Some Gross Features of Single-Particle Spectra at Energies above104GeV and Comparisons with Data at 28.5 GeV

Abstract

Single-particle spectra from multiparticle production in $\mathrm{pp}$ collisions at $28.5 \frac{\mathrm{GeV}}{c}$ from bubble-chamber data are compared with cosmic-ray emulsion data above ${10}^4$ GeV. The spectrum at high energies does not develop a plateau as expected from multiperipheral models, and the target-fragmentation cross section decreases, approximately as $\frac{1}{\ln s}$.
