A radiative neutrino mass model with hidden gauge symmetry inducing semi-annihilating dark matter
Abstract
We propose two-loop neutrino mass model with gauged hidden U(1) symmetry, and discuss a Majorana type of dark matter candidate that has semi-annihilation processes in the relic density as well as lepton flavor violations and muon anomalous magnetic moment. Also, we demonstrate global analysis to satisfy neutrino oscillation data, lepton flavor violations, and relic density of dark matter candidate and show that semi-annihilation modes play a crucial role in finding observed relic density.
