Antiproton-neutron interactions at 100 GeV/c - Liverpool-Stockholm-Vanderbilt Collaboration; Fry, J.R.; Noble, P.R.; Evans, W.H.; Moreton, A.; Ekspong, G.; Gennow, H.; Johansson, E.; Roos, C.; Fenker, H.; Marraffino, J.; Norrby, J.; et al. (Elsevier)
From an exposure of the 30-inch deuterium filled bubble chamber to a 100 GeV/c antiproton-enriched beam at FNAL, we have calculated the topological cross sections for antiproton-neutron interactions with three or more charged particles in the final state. A comparison of our data with pn data at the same momentum allows us to estimate the annihilation contribution to each multiplicity, and hence calculate the average value, and width, of the annihilation multiplicity distribution. Our results are consistent with those from pp data at 100 GeV/c, but depart from the trend of lower-energy pp data.
