The abundances of baryons and leptons are not only closely related to each other and to the generation of neutrino masses but may also be linked to the dark matter in the Universe. In this paper we review how a consistent physics beyond the Standard Model framework for cosmology and neutrino masses could arise by studying these interrelations.

Abstract We propose a scenario of spontaneous leptogenesis in Higgs inflation with help from two additional operators: the Weinberg operator (Dim 5) and the derivative coupling of the Higgs field and the current of lepton number (Dim 6). The former is responsible for lepton number violation and the latter induces chemical potential for lepton number. The period of rapidly changing Higgs field, naturally realized in Higgs inflation during the reheating, allows large enhancement in the produced asymmetry in lepton number, which is eventually converted into baryon asymmetry of the universe. This scenario is compatible with high reheating temperature of Higgs inflation model.
