Muon g???2 in U(1) μ? τ symmetric gauged radiative neutrino mass model

摘要

We explore muon anomalous magnetic moment (muong?2) in a scotogenic neutrino model with a gauged lepton number symmetryU(1)μ?τ. In this model, a dominant muong?2contribution comes not from an additional gauge sector but from a Yukawa sector. In our numericalΔχ2analysis, we show that our model is in favor of normal hierarchy with some features. We demonstrate one benchmark point, satisfying muong?2at the best fit value25.1×10?10.
