Direct leptogenesis

Research output: Contribution to journalConference articlepeer-review

Abstract

It is pointed out that lepton asymmetry can be generated through CP-preserving inflaton decay into Higgs boson when the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) matrix has a proper CP phase. The leptons produced during thermalization process undergo flavor oscillations where CP violation takes place. The llHH terms relevant to the active neutrino masses give lepton number violations. Our scenario can be tested from the ground-based neutrino experiment.
