Radiative dark matter and neutrino masses from an alternative U(1) B-L gauge symmetry
Original language description
We propose a model where the masses of the active neutrinos and a dark matter candidate are generated radiatively through the U(1)(B-L) gauge symmetry breaking. It is realized by a non-universal U(1)(B-L) charge assignment on the right handed neutrinos and one of them becomes DM. The dark matter mass becomes generally small compared with the typical mass of the Weak Interacting Massive Particles and we have milder constraints on the dark matter. We consider the case where the dark matter is produced through the freeze-in mechanism and show that the observed dark matter relic density can be realized consistently with the current experimental constraints on the neutrino masses and the lepton flavor structure.
