A minimal model of TeV scale WIMPy leptogenesis

Abstract

We present a minimal framework of $U(1{)}_{B-L}$ gauge extension of the Standard Model explaining dark matter abundance and matter-antimatter asymmetry simultaneously through an attractive mechanism of TeV scale WIMPy leptogenesis, testable at the current and next generation of colliders. This framework can also explain small neutrino masses via a radiative mechanism. One of the key predictions of this model is an enhanced rate for lepton flavor violating decay $\mu \to e\gamma$ within the sensitivity reach of next generation experiments.
