Abstract

NuTeV has performed precise measurements of neutral-current to charged-current cross section ratios using intense high energy neutrino and anti-neutrino beams on a primarily steel target at the Fermilab Tevatron. A null hypothesis test of the standard model allows the extraction sin²θ_W^νN(≡ 1-M_W²/M_Z²)=0.2277±0.0013(stat)±0.0009(syst), a value that differs from predictions of global electroweak fits by +3.0σ.
