Description

We summarize theoretical explanations of the three σ discrepancy between sin2θW measured by NuTeV and predicted by the standard model global fit. Possible new physics explanations (e.g., an unmized Z') are not compelling. The discrepancy would be reduced by a positive momentum asymmetry s- in the strange sea; present experimental estimates of s- are unreliable or incomplete. Upgrading the NuTeV analysis to NLO would alleviate concerns that the discrepancy is a QCD effect
