Total cross sections forνμnandνμpcharged-current interactions in the 7-foot bubble chamber

Abstract

The total cross sections for ..nu../sub ..mu../n and ..nu../sub ..mu../p charged-current interactions and their ratio R = sigma/sub T/(..nu..n)/sigma/sub T/(..nu..p) have been measured as a function of neutrino energy from 0.4 to 10 GeV. The experiment is performed using the BNL 7-foot deuterium bubble chamber exposed to the Alternating Gradient Synchrotron wide-band neutrino beam. The absolute values of the cross sections are normalized to the quasielastic scattering (..nu../sub ..mu../n..--> mu../sup -/p) cross section. Above 1.6 GeV the data are consistent with the quark-parton model. We find that sigma/sub T/(..nu..n)/E/sub ..nu../ = (1.07 +- 0.05) x 10/sup -38/, sigma/sub T/(..nu..p)/E/sub ..nu../ = (0.54 +- 0.04) x 10/sup -38/, and sigma/sub T/(..nu..N)/E/sub ..nu../ = (0.80 +- 0.03) x 10/sup -38/ cm/sup 2//GeV for = 3.2 GeV, and R = 1.95 +- 0.10 for = 3.7 GeV.
