AbstractBy extending the SM with two scalar singlets, a vector-like fermion doublet and a fermion singlet, all odd under a Z2 symmetry, it is possible to explain the correct dark matter relic density and also fulfill the main constraints for neutrino physics. In this work, we only consider the case of fermionic dark matter. We study the parameter space, first of all taking into account the relic density constraint, which gives us a set of parameters that can be used as inputs for the Casas-Ibarra parametrization in order to get the remaining parameters that also match neutrino physics. We also analyze possible constraints from lepton flavor violation processes such as μ→eγ.
