Deeply Inelastic Proton-Proton Collisions

Abstract

We measured the differential cross section for 12.4-GeV/c proton-proton inelastic scattering on circles of fixed energy loss in the c.m. system. We varied the inelasticity from 8 to 94% and covered much of the angular range. For essentially all inelasticities the dependence on ${{P}_{\ensuremath{\perp}}}^{2}$ is approximately ${e}^{\ensuremath{-}3{{P}_{\ensuremath{\perp}}}^{2}}$. The absolute value of $\frac{{d}^{2}\ensuremath{\sigma}}{d\ensuremath{\Omega}\mathrm{dp}}$ also depends only weakly on energy loss.
