Abstract
Proton-proton interactions with four or more charged particles in the final state are studied over a range of incident momenta between 13 and 28.5 GeV/c. Topology cross sections are presented. The center-of-mass momentum distributions of {pi}{sup +} and {pi}{sup -} are determined and are successfully parameterized. The {pi}{sup +} and {pi}{sup -} momentum spectra are found to have approximately the same shape. Multiple fireball production is not required by our data.
