A neutrino mass model with hidden U(1) gauge symmetry

Abstract We propose a realisation of inverse seesaw model controlled by hidden U ( 1 ) gauge symmetry, and discuss the impact of a bosonic dark matter (DM) candidate by imposing a Z 2 parity. We present the detail of scalar spectra and apply the Casas-Ibarra parametrisation to fit the neutrino oscillation data. For this model, the allowed region is extracted to explain the observed relic density and the muon g − 2 discrepancy, satisfying flavor constraints with DM involved. We interpret the DM annihilation into f ¯ f including all SM charged fermion pairs and investigate the direct detection to place the bound on DM-Higgs coupling. Finally the LHC DM production is explored in light of charged lepton pair signature plus missing transverse energy.
