Results are presented on neutral production in (pi)-p interactions at 250 GeV/c. The data was obtained from a 46,000 picture exposure of the liquid hydrogen filled 15 foot bubble chamber at Fermi National Accelerator Laboratory. A total of 22,330 beam interactions and 25,110 candidate gammas were found in the film. Semi-inclusive cross sections were obtained for 2 through 24 charged particle topologies. The production vertex and all associated gammas were measured in 45% of the interactions having one or more candidate gammas. The neutral pion multiplicity distribution was obtained as a function of charged topology and for all charged topologies using the scan information on gamma production. The total neutral pion multiplicity was found to be equivalent to 1/2 the produced charged pion multiplicity. The total (charged plus neutral) non-strange multiplicity distribution was obtained for 0 to 15 particles. The total multiplicity was found to display evidence of oscillatory behaviour with the final state more likely to contain even numbers of particles than odd. Neutral pion longitudinal and transverse momentum and rapidity distributions were obtained from the measured gamma momentum distributions. This experiment was the first hadrom study in the FNAL 15 foot bubble chamber and presents the first data on semi-inclusive neutral pion and total multiplicities at high energies. / Source: Dissertation Abstracts International, Volume: 43-12, Section: B, page: 4030. / Thesis (Ph.D.)--The Florida State University, 1982.
