Fermion masses and mixings in SO(10) GUTs
arXiv:hep-ph/0602166
Abstract
I will present a simple, economic and predictive model of Yukawa structures in the context of a renormalizable SO(10) grandunification. The righthanded neutrino mass is generated radiatively. The fermions have Yukawa couplings with one 10 and one 120 dimensional Higgses. In the approxiamate two generation scenario the model predicts degenerate neutrinos, small quark mixing and b-tau Yukawa unification.
