A Precise Determination of Electroweak Parameters in Neutrino-Nucleon Scattering

Abstract

The NuTeV collaboration has extracted sin2thetaW from the ratios of neutral current to charged current neutrino and anti-neutrino cross-sections. Our value, sin2thetaW(on-shell)=0.2277+/-0.0013(stat)+/-0.0009(syst), is three standard deviations above the standard model prediction. We also present a model independent analysis of the same data.
