Resonant leptogenesis at TeV-scale and neutrinoless double beta decay
Resonant leptogenesis at TeV-scale and neutrinoless double beta decay
We investigate a resonant leptogenesis scenario by quasi-degenerate right-handed neutrinos which have TeV-scale masses. Especially, we consider the case when two right-handed neutrinos are responsible to leptogenesis and the seesaw mechanism for active neutrino masses, and assume that the CP violation occurs only in the mixing matrix of active neutrinos. …
