Abstract
We point out that what can be considered as the most natural implementation of type-II seesaw in SO(10) naturally leads to a leptogenesis scenario that is significantly more predictive than usual. The baryon asymmetry depends on the low-energy neutrino parameters, with no unknown seesaw-scale flavour parameters involved. In particular, the necessary CP violation is provided by the CP-violating phases of the lepton mixing matrix.File in questo prodotto:
