We are considering possible UV completions of the scotogenic neutrino model which is a bottom-up attempt to explain both neutrino masses and dark matter with additional weak scalar triplet, charged scalar singlet and 3 generations of vector-like lepton doublets. Neutrino masses are generated radiatively at the one-loop level (variation of the Zee model) while the neutral triplet component can serve as a dark matter candidate.
Preliminary studies show that while such scenario could easily be embedded into SU(5) framework, the GUT scale might be difficult to reconcile with the proton lifetime bounds.
