@article{Fiaschi2018SingletdoubletFA, title={Singlet-doublet fermion and triplet scalar dark matter with radiative neutrino masses}, author={Juri Fiaschi and Michael Klasen and Simon May}, journal={Journal of High Energy Physics}, year={2018}, volume={2019}, pages={1-24} }

A bstractWe present a detailed study of a combined singlet-doublet fermion and triplet scalar model for dark matter. These models have only been studied separately in the past. Together, they form a simple extension of the Standard Model that can account for dark matter and explain the existence of neutrino masses, which are generated radiatively. This holds even if singlet-doublet fermions and triplet scalars never contribute simultaneously to the dark matter abundance. However, this also…
