As its application, we consider a scenario for leptogenesis based on the lepton number asymmetry generated in the right-handed neutrino sector through the inflaton decay. The scenario is examined in a one-loop radiative neutrino mass model extended with singlet scalars. © 2017 American Physical Society., 金沢大学理工研究域数物科学系}, title = {Symmetry restoration due to preheating and lepton number asymmetry}, volume = {96}, year = {2017} }
