%0 Journal Article %T Fermion masses and symmetry breaking of a U(2) flavour symmetry %A Riccardo Barbieri %A Leonardo Giusti %A Lawrence J. Hall %A Andrea Romanino %J Physics %D 1998 %I arXiv %R 10.1016/S0550-3213(99)00195-9 %X We show how a specific sequential breaking pattern of a U(2) flavour symmetry occurs automatically in a broad framework. The relative orientation in U(2) space of the spurion fields that breaks the U(2) symmetry is uniquely fixed, thus determining the form of the fermion mass matrices in a predictive way. %U http://arxiv.org/abs/hep-ph/9812239v1
