Leptogenesis from the Dirac CP-violating phase in the minimal left-right symmetric model
Xueke Chen, Xinyi Zhang
Leptogenesis from low-energy CP violation provides a vital link between neutrino physics and the observed baryon asymmetry of the universe. However, this connection is typically ob…

Neutrino reheating predictions with non-thermal leptogenesis
Xinyi Zhang
Connecting inflation with neutrino physics through non-thermal leptogenesis via direct inflaton-right-handed neutrino (RHN) coupling naturally incorporates neutrino reheating, leav…

Towards a systematic study of non-thermal leptogenesis from inflaton decays
Xinyi Zhang
This paper investigates non-thermal leptogenesis from inflaton decays in the minimal extension of the canonical type-I seesaw model, where a complex singlet scalar is introduc…
