Description

Using the particle content of the Altarelli-Feruglio model as a paradigm, we generalize the family symmetry A4 x Z3 to all 1048 groups of order less than or equal to 100 and derive the Lagrangian for the lepton sector, the mixing matrices, and finally the mixing angles. We compare our findings to experimental data and identify the cases (i) where tribimaximal mixing occurs, (ii) where the mixing angles are in agreement with the experimental constraints. We explain the calculational tools that we have used and that we believe to be useful for model building. In particular, we work out one example in detail to illustrate our general approach.
