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

We explore muon anomalous magnetic moment (muon g - 2) in a scotogenic neutrino model with a gauged lepton number symmetry U(1)(mu-tau). In this model, a dominant muon g - 2 contribution comes not from an additional gauge sector but from a Yukawa sector. In our numerical Delta chi(2) analysis, we show that our model is in favor of normal hierarchy with some features. We demonstrate one benchmark point, satisfying muon g - 2 at the best fit value 25.1 x10(-10). (C) 2021 The Author(s). Published by Elsevier B.V.

Automated summary

In this study, a scotogenic neutrino model with a gauged lepton number symmetry U(1)(mu-tau) is employed to investigate the muon anomalous magnetic moment (muon g - 2), revealing that the dominant contribution to muon g - 2 comes from the Yukawa sector rather than an additional gauge sector. The numerical Delta chi(2) analysis shows that the model favors the normal hierarchy and presents a benchmark point that satisfies the muon g - 2 at the best fit value 25.1 x10(-10).
