Leptogenesis within a predictive G(224)/SO(10)-framework

A G(224)/SO(10)-framework has been proposed (a few years ago) that successfully describes the masses and mixings of all fermions including neutrinos. Baryogenesis via leptogenesis is considered within this framework by allowing for natural phases ({approx} 1/30-1/2) in the entries of the Dirac and Majorana mass-matrices. It is shown that the framework leads quite naturally to the desired magnitude for the baryon asymmetry, in full accord with the observed features of atmospheric and solar neutrino oscillations, as well as with those of quark and charged lepton masses and mixings. Hereby one obtains a unified description of fermion masses, neutrino oscillations and baryogenesis within a single predictive framework.
