Comparison of nuclear effects in high energy leptonic and hadronic scattering

A neutrino-Neon (antineutrino-Neon) scattering experiment using the Fermilab 15 foot bubble chamber for analysis is compared with a pi plus- (pi minus)-Neon scattering experiment at 30 and 64 GeV/c in the CERN BEBC bubble chamber. The comparison analyzes nuclear effects, excluding the EMC effect. The Fermilab neutrino experiment (E546) used a Ne-H2 (47% atomic Ne) mixture at 29.50 Kelvin and a density of 0.56 gm/cc. Charged current events had the muon identified by the External Muon Identifier. The average neutrino energy was 90 GeV, and the ratio of neutrino to antineutrino induced events was approximately 6:1. All events were fully measured. The CERN pion experiment (WA51) used a Ne-H2 (60% atomic Ne) mixture at 29.150 Kelvin and density of 0.71 gm/cc. The 36K pictures obtained were fully scanned, and positive, negative, identified proton, and straight track multiplicities recorded for all accepted events. A sample of approximately 1200 events at 30 GeV/c had all charged tracks measured. Average multiplicity and dispersion are linearly related. Identified proton multiplicities agree well with the prediction of the Andersson model. Multiplicity correlations with identified protons are studied. KNO scaling distributions, fits to multiplicities as functions of W2 and Q2 and the behavior of various moments with energy are presented
