Minimal effective theory for leptogenesis, dark matter, and neutrino masses

Abstract

We study the phenomenology of choosing a minimal set of effective operators simultaneously generating the dark matter relic density and matter-antimatter asymmetry of the universe. Neutrino masses are obtained in a specific case of baryogenesis via leptogenesis. We find that only two new particles -- a heavy unstable fermion and a light dark matter scalar -- need to be included in addition to the Standard Model particle content.
