Abstract

NuTeV measures sin2 θW by comparing neutral and charged current cross-sections on a heavy nuclear target, and finds a value of sin2 θW(on-shell) = 0.2277 ± 0.0013(stat) ± 0.0009(syst), approximately 3σ from the predicted value. We discuss the possibility that nuclear effects on parton distribution functions or cross-sections may be responsible for the discrepancy.
