Radiative Two-Loop Neutrino Masses with Dark Matter
C. Simoes, D. Wegman
Using the Weinberg operator, we present a full collection of genuine two-loop models for neutrino mass generation, which contain a dark matter particle as one of the internal messe…

Radiative accidental matter
D. Aristizabal Sierra, C. Simoes, D. Wegman
Accidental matter models are scenarios where the beyond-the-standard model physics preserves all the standard model accidental and approximate symmetries up to a cutoff scale relat…

Closing in on minimal dark matter and radiative neutrino masses
D. Aristizabal Sierra, C. Simoes, D. Wegman
We study one-loop radiative neutrino mass models in which one of the beyond-the-standard model fields is either a hypercharge-zero fermion quintet (minimal dark matter) or a hyperc…
