Thermal Wash-in Leptogenesis via Heavy Higgs Decay (2405.14332v2)

Published 23 May 2024 in hep-ph

Abstract: We present a conceptually simple model to generate asymmetries that are not directly related to baryon nor lepton charges. The model employs a three-Higgs doublet framework, wherein the other two Higgs fields are significantly heavier than the Standard Model (SM) Higgs field. The decay of these heavier Higgs fields generates asymmetry for approximately conserved charges in the Standard Model at a high temperature. These asymmetries will be converted into baryon/lepton asymmetry through $B-L$ violating interactions associated with right-handed neutrinos via the wash-in mechanism.
