Description

Features of a predictive SO(10) GUT model with lopsided mass matrices, which fits well the present quark and lepton mass and mixing data, are briefly reviewed. With the near degeneracy of the lightest two right-handed neutrinos required in the model to obtain the LMA solar neutrino solution, resonant enhancement of leptogenesis is strongly suggested. The amounts of lepton asymmetry and subsequent baryon asymmetry are determined with both the conventional type I and proposed type III seesaw mechanisms.
