  We consider a dark matter (DM) model that arises from the interplay of two
simplified dark matter models, namely the doublet-triplet fermion model and the
doublet-triplet scalar model. Despite being excellent exponents of the WIMP
paradigm, the physics related to DM in each of these models fails at the same
time to account for neutrino masses. It turns out that from the combination of
these two models it is possible to generate neutrino masses at one-loop level
in the four topologies that are realizations of the Weinberg operator for
neutrino masses at one-loop. In this work, we combine both models focusing
mostly on fermionic dark matter lying at the electroweak scale. We analyze the
impact of the extra charged fields on the Higgs diphoton decay and find that,
thanks to the presence of the charged scalars, it is possible to have a viable
DM region at the electroweak scale.
