Electroweak Physics Results from NuTeV
Tim Bolton
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 2θWνN( 1-MW2/MZ2)=0.22770.0013(stat)0.0009(syst), a value that differs from predictions of global electroweak fits by +3.0σ.
