SO(10) grand unification model with S4 flavor symmetry

We present a supersymmetric grand unification model based on SO(10) group with S4 flavor symmetry. In this model, the fermion masses are from Yukawa couplings involving 10 and (126) over bar Higgs multiplets and the flavor structures of mass matrices of both quarks and leptons are determined by spontaneously broken S4. This model fits all of the masses and mixing angles of the quarks and leptons. For the most general CP-violation scenario, this model gives sin theta(13) a wide range of values from zero to the current bound with the most probable values 0.02-0.09. With certain assumptions where leptonic phases have same CP-violation source as CKM phase, one gets a narrower range 0.03-0.06 for sin theta(13) with the most probable values 0.04-0.08. This model gives leptonic Dirac CP phase the most probable values 2-4 radians in the general CP-violation case.
