Models with radiative neutrino masses and viable dark matter candidates

Understand

We provide a list of particle physics models at the TeV-scale that are compatible with neutrino masses and dark matter.

• In these models, the Standard Model particle content is extended with a small number (\leq 4) of scalar and fermion fields transforming as singlets, doublets or triplets under SU(2), and neutrino masses are generated radiatively via 1-loop diagrams.
• The dark matter candidates are stabilized by a Z_2 symmetry and are in general mixtures of the neutral components of such new multiplets.
• We describe the particle content of each of these models and determine the conditions under which they are consistent with current data.
