We study the dark matter phenomenology of scotogenic frameworks through a rather illustrative model extending the Standard Model by scalar and fermionic singlets and doublets. Such a setup is phenomenologically attractive since it provides the radiative generation of neutrino masses, while also including viable candidates for cold dark matter. We employ a Markov Chain Monte Carlo algorithm to explore the associated parameter space in view of numerous constraints stemming from the Higgs mass, the neutrino sector, dark matter, and lepton-flavour violating processes. After a general discussion of the results, we focus on the case of fermionic dark matter, which remains rather uncovered in the literature so far. We discuss the associated phenomenology and show that in this particular case a rather specific mass spectrum is expected with fermion masses just above 1 TeV. Our study may serve as a guideline for future collider studies.

“…A discrete Z 2 symmetry ensures that the dark matter particle is stable. In a sens, this corresponds to a union of the singlet-doublet scalar [21][22][23][24] and singlet-doublet fermion [21,22,[25][26][27][28] extensions. More recently, this model has been studied in Ref.…”

“…For the doublets, the decompositions according to the physical charges Q = T 3 +Y 2 have also been indicated. It is evident that the model can be seen as a combination of the singlet-doublet scalar [32][33][34][35] and the singlet-doublet fermion dark matter model [32,33,[36][37][38], which have both well been studied separately. Our model allows in addition for the radiative generation of neutrino masses.…”

We present a detailed study of a combined singlet-doublet scalar and singletdoublet fermion model for dark matter. These models have only been studied separately in the past. We show that their combination allows for the radiative generation of neutrino masses, but that it also implies the existence of lepton-flavour violating (LFV) processes. We first analyse the dark matter, neutrino mass and LFV aspects separately. We then perform two random scans for scalar dark matter imposing Higgs mass, relic density and neutrino mass constraints, one over the full parameter space, the other over regions where scalar-fermion coannihilations become important. In the first case, a large part of the new parameter space is excluded by LFV, and the remaining models will be probed by XENONnT. In the second case, direct detection cross sections are generally too small, but a substantial part of the viable models will be tested by future LFV experiments. Possible constraints from the LHC are also discussed.
