Overview

Neutrinos are very light fermions, a fact that can be well understood if their masses are induced at loop level. Many radiative neutrino mass models have been proposed along the years. The Scotogenic model is a very economical and popular setup that induces Majorana neutrino masses at the 1-loop level and includes a viable dark matter candidate. Based on the original model, many variants can be constructed.
We discuss specific variations of the Scotogenic model with alternative representations under the Standard Model gauge group and additional Scotogenic states, perhaps coming from ultraviolet extended setups.
These variants of the Scotogenic paradigm have novel phenomenological predictions and may explain some long-standing anomalies.
