@article{Fong2014LeptogenesisIS, title={Leptogenesis in SO(10)}, author={Chee Sheng Fong and Davide Meloni and Aurora Meroni and Enrico Nardi}, journal={Journal of High Energy Physics}, year={2014}, volume={2015}, pages={1-21} }

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…
