The Determination of $\sin^2 \theta_W$ in Neutrino Scattering: no more anomaly

TL;DR

This paper reviews corrections to the NuTeV measurement of sin^2 θ_W, demonstrating that when properly accounted for, the results align with the Standard Model, removing previous claims of anomaly.

Contribution

It clarifies the impact of charge symmetry violation and iso-vector nuclear force corrections on the NuTeV sin^2 θ_W measurement, resolving prior anomalies.

Findings

Corrections eliminate the previously claimed anomaly in NuTeV sin^2 θ_W measurement.

Proper inclusion of nuclear effects aligns results with the Standard Model.

The measurement is consistent with theoretical expectations after corrections.

Abstract

We review the corrections to the NuTeV determination of sin2 qW, concluding that it is no longer appropriate to present it as an "anomaly". Indeed, when well understood corrections associated with charge symmetry violation and the iso-vector nuclear force are properly included, the measurement is completely consistent with the Standard Model.
