Scale-Invariant Models with One-Loop Neutrino Mass and Dark Matter Candidates

Understand

We construct a list of minimal scale-invariant models at the TeV scale that generate one-loop neutrino mass and give viable dark matter candidates.

• The models generically contain a singlet scalar and a $Z_2$-odd sector comprised of singlet, doublet and/or triplet SU(2) multiplets.
• The dark matter may reside in a single multiplet or arise as an admixture of several multiplets.
• We find fifteen independent models, for which the dark matter is a viable candidate and neutrino mass results from a diagram with just one of the irreducible scale-invariant one-loop topologies.
