Scotogenic Seesaw Mechanism and DiscreteGauge Symmetries

We study the gauged U(1)B–L extensions of the models for neutrino
masses and dark matter. In this class of models, tiny neutrino masses are radiatively induced through the loop diagrams, while the origin of the dark matter stability is guaranteed by the remnant of the gauge symmetry.
Depending on how the lepton number conservation is violated, these models are systematically classified.
