The NuTeV Anomaly, Neutrino Mixing, and a Heavy Higgs

Abstract

Recent data from NuTeV prefer a heavy Higgs in contrast to the LEP/SLD data which prefer a light Higgs. I argue that if the Z-nu-nu coupling is suppressed, as would be the case if the neutrinos mixed with a heavy gauge singlet state, then both sets of data will be consistent with a heavy Higgs.
