Fermion mass hierarchies and flavor mixing from T′ symmetry

We construct a supersymmetric model based on T-'circle times Z(3)circle times Z(9) flavor symmetry. At the leading order, the charged lepton mass matrix is not diagonal, T-' is broken completely, and the hierarchy in the charged lepton masses is generated naturally. Nearly tribimaximal mixing is predicted, and subleading effects induce corrections of order lambda(2), where lambda is the Cabibbo angle. Both the up quark and down quark mass matrices' textures of the well-known U(2) flavor theory are produced at the leading order; realistic hierarchies in quark masses and Cabibbo-Kobayashi-Maskawa matrix elements are obtained. The vacuum alignment and subleading corrections are discussed in detail.
