Freeze-in Dirac neutrinogenesis: thermal leptonic CP asymmetry
Abstract We present a freeze-in realization of the Dirac neutrinogenesis in which the decaying particle that generates the lepton-number asymmetry is in thermal equilibrium. As the right-handed Dirac neutrinos are produced non-thermally, the lepton-number asymmetry is accumulated and partially conve...
