Scaling-Variable Distributions for Antineutrino-Nucleon Interactions

Abstract

New data are reported on high-energy antineutrino interactions obtained using the Fermilab 15-ft bubble chamber filled with a light neon-hydrogen mixture. The new data support a gentle energy dependence for the $y$ distribution consistent with the trend of the existing data, but show no evidence for a marked energy threshold. The data for $〈x〉$ and $〈v〉=〈\mathrm{xy}〉$ show some decrease with increasing energy which may be related to scaling deviations measured in electron and muon experiments.
