Quark masses and mixing with A4 family symmetry

The successful A4 family symmetry for leptons is applied to quarks, motivated by the quark-lepton assignments of SU(5). Realistic quark masses and mixing angles are obtained, in good agreement with data. In particular, we find a strong correlation between vertical bar V-ub vertical bar and the CP phase beta, thus allowing for a decisive future test of this model. (c) 2006 Elsevier B.V.
