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