Neutrino mass and $(g-2)_{mu}$ with dark $U(1)_D$ symmetry

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 $(g-2)_{mu}$ indicating $4.2~ sigma$ deviation from the SM prediction, we examine how the deviation $Delta a_{mu}$ can be explained in this model.
