Abstract

We propose an extension of the Standard Model (SM) for radiative neutrino mass by introducing a dark U(1)_D gauge symmetry. The kinetic mixing between the SM gauges and the dark U(1)_D gauge arises at 1-loop mediated by new inert scalar fields. We show that the tiny neutrino mass and dark matter candidates are naturally accommodated. Motivated by the recent measurement of (g-2)_μ indicating 4.2~ σ deviation from the SM prediction, we examine how the deviation Δa_μ can be explained in this model.
