Title: Reassessment of the NuTeV determination of the weak mixing angle

Abstract

In light of the recent discovery of the importance of the isovector EMC effect for the interpretation of the NuTeV determination of sin 2θ W, it seems timely to reassess the central value and the errors on this fundamental Standard Model parameter derived from the NuTeV data. We also include earlier work on charge symmetry violation and the recent limits on a possible asymmetry between s and s¯ quarks. In addition, with these corrections we find a revised NuTeV result of sin 2θ W = 0.2232 ± 0.0013(stat) ± 0.0024(syst), which is in excellent agreement with the running of sin 2θ W predicted by the Standard Model.
