We investigate the scenario of resonant thermal leptogenesis, in which the leptonic asymmetries are generated through renormalization group corrections induced at the leptogenesis scale. In the framework of the standard model extended by three right-handed heavy Majorana neutrinos with masses M1 = M2 ≪ M3 at some high scale, we show that the mass splitting and CP -violating effects induced by renormalization group corrections can lead to values of the CP asymmetries large enough for a… CONTINUE READING
