θ13, rare decays and leptonic CP violation

We introduce a flavor U(1) symmetry à la Froggat-Nielsen to explain the magnitude of the CKM mixing angles as well bilarge mixing in the neutrino sector. In the framework of GUTs we also estimate the magnitude of the third leptonic mixing angle θ13. Estimates for rare leptonic decays such as μ→eγ are also provided. Finally, leptogenesis is exploited for estimating the magnitude of leptonic CP violation.
