Content
I will concentrate on the link between leptogenesis and low-energy neutrino data, showing how the baryon asymmetry of the Universe can constrain a type- I seesaw model and yield interesting predictions on the neutrino parameters. To this aim, I will consider the conditions required by strong thermal leptogenesis, where the final asymmetry is fully independent of the initial conditions. In this framework, barring strong cancellations in the seesaw formula and in the
flavoured decay parameters, a lightest neutrino mass m1 10 meV for normal ordering and m1
3 meV for inverted ordering are favoured. Finally, I will
briefly comment on the even richer predictions of SO(10)-inspired leptogenesis models and on the present experimental evidences.
