Two Loop Neutrino Model with Dark Matter and Leptogenesis

Understand

We study a two-loop induced radiative neutrino model at TeV scale with global $U(1)$ symmetry, in which we analyze dark matter and resonant leptogenesis.

• The model includes two kinds of dark matter candidates.
• We discuss what kind of dark matter can satisfy the observed relic density as well as the current direct detection bound, and be simultaneously compatible with the leptogenesis.
• We also discuss whether our resonant leptogenesis can be differentiated from the other scenarios at TeV scale or not.
