We analyze the consistency of electroweak breaking, neutrino and dark matter phenomenology within the simplest scoto-seesaw model. The scoto-seesaw model can be obtained by adding the minimal dark sector to the simplest “missing partner” type-I seesaw. This way one has a physical picture for the neutrino oscillation lengths: the “atmospheric” mass scale arises from the tree-level seesaw, while the “solar” scale is induced radiatively, mediated by the dark sector. One also has a lower bound for the neutrinoless double beta decay amplitude 1 .
