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.
