The NuTeV Anomaly, Neutrino Mixing, and a Heavy Higgs

TL;DR

The paper proposes that neutrino mixing with a heavy singlet state can reconcile NuTeV and LEP/SLD data, both favoring a heavy Higgs, by suppressing the Z-nu-nu coupling.

Contribution

It introduces a neutrino mixing mechanism with a heavy singlet to resolve the Higgs mass discrepancy between experiments.

Findings

Suppressed Z-nu-nu coupling aligns NuTeV and LEP/SLD data with a heavy Higgs.

Neutrino mixing with a heavy singlet can explain the experimental preferences.

The model provides a consistent framework for Higgs mass interpretation.

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.
