Insights on the Scale of Leptogenesis from Neutrino Masses and Neutrinoless Double-Beta Decay

Alessandro Granelli, Koichi Hamaguchi, Maura E. Ramirez-Quezada +3

We revisit the thermal leptogenesis scenario in the type-I seesaw framework featuring three heavy Majorana neutrinos with a hierarchical mass spectrum. We focus on low energy obser…
