Scotogenic R\nuMDM at Three-Loop Level

TL;DR

This paper introduces a three-loop radiative neutrino mass model combining minimal dark matter fields with a two-Higgs-doublet model, predicting new fermions and scalars that could be detected at colliders.

Contribution

It presents a novel three-loop neutrino mass model integrating fermion and scalar multiplets from minimal dark matter, with implications for collider searches.

Findings

Model induces neutrino masses at three-loop level.

Predicts fermion quintuplets and scalar septuplets detectable at colliders.

Estimates collider discovery potential for new particles.

Abstract

We propose a model in which the radiative neutrino (R\nu) masses are induced by fermion quintuplet and scalar septuplet fields from the minimal-dark-matter (MDM) setup. In conjunction with the 2HDM fields, on top of which our model is built, these hypercharge zero fields and additional scalar quintuplet lead to an accidental DM-protecting Z_2 symmetry and establish the R\nuMDM model at the three-loop level. We assess the potential for discovery of quintuplet fermions on present and future pp colliders.
