Description
We extend the work of Carone, Chaurasia and Vasquez on non-supersymmetric models of flavor
based on the double tetrahedral group. Three issues are addressed: (1) the sector of flavorsymmetry-breaking fields is simplified and their potential studied explicitly, (2) a flavorful axion is
introduced to solve the strong CP problem and (3) the model is extended to include the neutrino
sector. We show how the model can accommodate the strong hierarchies manifest in the charged
fermion Yukawa matrices, while predicting a qualitatively different form for the light neutrino mass
matrix that is consistent with observed neutrino mass squared differences and mixing angles
