||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.
