Title: Extended Zee model for neutrino mass, leptogenesis, and sterile-neutrino-like dark matter

Abstract

We propose an extension of the standard model with a U(1){sub B-L} global symmetry that accommodates radiative neutrino masses along with dark matter and leptogenesis. The observed matter-antimatter asymmetry of the Universe is generated through the leptogenesis route keeping the U(1){sub B-L} symmetry intact. The B-L global symmetry is then softly broken, providing the subeV neutrino masses. The model then incorporates a MeV scale sterile-neutrino-like dark matter.
