摘要：

We present a complete analysis of the fermion masses and mixing matrices in the framework of the little flavon model. In this model textures are generated by coupling the fermions to scalar fields, the little flavons, that are pseudo Goldstone bosons of the breaking of a global SU(6) symmetry. The Yukawa couplings arise from the vacuum expectation values of the flavon fields, their sizes controlled by a potential in the manner of Coleman and Weinberg. Quark and lepton mass hierarchies and mixing angles are accommodated within the effective approach in a natural manner.
