Freeze-in leptogenesis without the need for right-handed neutrino oscillations
Martin A. Mojahed, Sascha Weber
We present an experimentally testable leptogenesis mechanism based on the standard type-I seesaw model that successfully operates at right-handed-neutrino (RHN) masses around the G…

Impact of dim-6 SMEFT operators on low-scale leptogenesis
Kaori Fuyuto, Julia Harz, Sascha Weber
We investigate the impact of higher-dimensional operators on low-scale leptogenesis (LG) via oscillations of right-handed neutrinos within the neutrino-extended Standard Model Effe…
