Precise Determination of Electroweak Parameters in Neutrino-Nucleon Scattering

Abstract

A systematic error in the extraction of ${\sin }^2{\theta }_W$ from nuclear deep inelastic scattering of neutrinos and antineutrinos arises from higher-twist effects arising from nuclear shadowing. We explain that these effects cause a correction to the results of the recently reported significant deviation from the Standard Model that is potentially as large as the deviation claimed, and of a sign that cannot be determined without an extremely careful study of the data set used to model the input parton distribution functions.
