Conventional Physics Explanations for the NuTeV sin2ThetaW

Abstract

The NuTeV experiment has measured sin^2Theta_W = 0.2277 +/- 0.0013(stat) +/- 0.0009(syst), approximately 3 standard deviations above the standard model prediction. This discrepancy has motivated speculation that the NuTeV result may be affected significantly by neglected experimental or theoretical effects. We examine the case for a number of proposed explanations.
