TL;DR
This paper reports a precise measurement of the electroweak parameter sin^2theta_W using neutrino-nucleon scattering data, revealing a significant deviation from the standard model prediction.
Contribution
It provides a new, highly accurate determination of sin^2theta_W and offers a model-independent analysis of the data, highlighting potential discrepancies with the standard model.
Findings
Measured sin^2theta_W(on-shell)=0.2277±0.0013(stat)±0.0009(syst)
Result is three standard deviations above the standard model prediction
Includes a model-independent analysis of neutrino scattering data
Abstract
The NuTeV collaboration has extracted sin^2theta_W from the ratios of neutral current to charged current neutrino and anti-neutrino cross-sections. Our value, sin^2theta_W(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.
