A bstractWe consider SO(10) Grand Unified Theories (GUTs) with vacuum expectation values (vevs) for fermion masses in the 10+126¯$$ \mathbf{10}+\overline{\mathbf{126}} $$ representation. We show that the baryon asymmetry generated via leptogenesis is completely determined in terms of measured low energy observables and of one single high energy parameter related to the ratio of the 10 and 126¯$$ \overline{\mathbf{126}} $$ SU(2) doublet vevs. We identify new decay channels for the heavy Majorana…

Successful N2 leptogenesis with flavour coupling effects in realistic unified models

In realistic unified models involving so-called SO(10)-inspired patterns of Dirac and heavy right-handed (RH) neutrino masses, the lightest right-handed neutrino N1 is too light to yield successful…

Flavour effects in gravitational leptogenesis

Within the Type-I seesaw mechanism, quantum effects of the right-handed (RH) neutrinos in the gravitational background lead to an asymmetric propagation of lepton and anti-leptons which induces a…
