Radiative leptogenesis in minimal seesaw models
Joaquim, F. R.
Original · EN
In the framework of seesaw models with only two heavy Majorana neutrinos, nonzero leptonic asymmetries can be radiatively generated when exact heavy neutrino mass degeneracy (M₁=M₂=M) is imposed at a scale ΛD > M. For a specific case, we show that an acceptable value for the baryon asymmetry of the Universe can be obtained considering thermal leptogenesis.
