摘要
In this paper we work in the framework of a radiative seesaw model with triplet fermion Sigma. Due to the Z(2) discrete flavor symmetry, the lightest neutral component of Sigma is stable and thus can be a dark matter candidate. Its mass can be solely determined by the dark matter relic abundance, which is bout 2.594 TeV. It can still constitute 30% of the dark matter when considering constraints from dark matter indirect detection experiments. The model also predict a dark matter-nucleus scattering cross-section that would be accessible with future dark matter direct detection searches. We further investigate constraints on the parameter space of the model from the lepton-flavor-violating processes and neutrino transition magnetic moments, induced by the Yukawa interaction of the Sigma with the left-handed lepton doublets.
