Measurement of y-Distributions for High Energy Antineutrino Scattering in Hydrogen-Neon

PDF Version Also Available for Download.

Description

Distributions in the scaling variable y are presented based on a study of approximately 700 antineutrino events in the energy range 10-200 GeV obtained using the Fermilab 15-ft bubble chamber filled with a light Hydrogen-Neon mixture. The distributions are inconsistent with a (1 -y){sup 2} form predicted by the simple quark parton model of the nucleon without antiquarks, but can be well fitted assuming a relative antiquark contribution of (10 {+-} 5)%. For small values of the Bjorken scaling variable (x < 0.1) the y-distribution can be well fitted assuming a relative antiquark contribution of (20 {+-} 5)%. For events ... continued below

For small values of the Bjorken scaling variable (x < 0.1) the y-distribution can be well fitted assuming a relative antiquark contribution of (20 {+-} 5)%. For events at small x in the energy range 30-200 GeV the y-distribution is in good agreement with the results reported by the HPWF group.
