Revisiting the R$\nu$MDM Models

Abstract

Combining neutrino mass generation and a dark matter candidate in a unified model has always been intriguing. We revisit the class of R$\nu$MDM models, which incorporate minimal dark matter in radiative neutrino mass models based on the one-loop ultraviolet completions of the Weinberg operator. The possibility of an exact accidental $Z_2$ is completely ruled out in this scenario. We study the phenomenology of one of the models with an approximate $Z_2$ symmetry. In addition to the Standard Model particles, it contains two real scalar quintuplets, one vector- like quadruplet fermion and a fermionic quintuplet. The neutral component of the fermionic quintuplet serves as a good dark matter candidate which can be tested by the future direct and indirect detection experiments. The constraints from flavor physics and electroweak-scale naturalness are also discussed.
