Charged multiplicity distributions and neutral particle production in 14.75 GeV/c pp interactions

From an exposure of the Brookhaven National Laboratory 80-inch hydrogen bubble chamber to a 14.75 GeV/s separated anti-proton beam we have determined an average charged particle multiplicity of 4.12±0.06. We have also studied the inclusive production of γ, K_S^o, and Λ^o particles. The correlations between π^± and π^o, K_S^o, or Λ^o are described and the strong correlation observed between π^± and π^o is contrasted to the apparent lack of correlation found in other hadron-hadron interactions at similar beam momenta. Invariant cross sections for γ, K_S^o, and Λ^o production are presented as a function of x.
