Scotogenic RνMDM at three-loop level

We propose a model in which the radiative neutrino (Rν) 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 quintupl...

Description
Summary:We propose a model in which the radiative neutrino (Rν) 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 Z2 symmetry and establish the RνMDM model at the three-loop level. We assess the potential for discovery of quintuplet fermions on present and future pp colliders.
