Measurement of elastic. nu. /sub. mu. / and nu-bar/sub. mu. / scattering on protons

Journal Article · · Phys. Rev. D; (United States)
We have measured elastic ..nu../sub ..mu../ and nu-bar/sub ..mu../ scattering on protons at the Brookhaven National Laboratory Alternating Gradient Synchrotron. We find R/sub NC/ = sigma(nu-bar/sub ..mu../p..-->..nu-bar/sub ..mu../p) / sigma(..nu../sub ..mu../p..--> nu../sub ..mu../p) = 0.44 +- 0.12 and R/sub numu/ = sigma(..nu../sub ..mu../p..--> nu../sub ..mu../p)/sigma(..nu../sub ..mu../n..--> mu../sup -/p) = 0.11 +- 0.03. The elastic Q/sup 2/ distribution is in good agreement with present knowledge of form factors and the Weinberg-Salam model. We find sin/sup 2/theta/sub W/ = 0.26 +- 0.06.
