Descripción
We discuss the masses and mixings of Quarks and leptons as the realization of an S(3) flavour permutational symmetry. In this model the flavour S(3) symmetry is left unbroken and the concept of flavour is extended to the Higgs sector by introducing in the theory three Higgs fields which are SU(2) doublets. The mass matrices of fermions are reparametrized in terms of their eigenvalues, and explicit analytical expressions for the flavour mixing angles are obtained. If the masses of the three right handed neutrinos are assumed to be different, non-degenerate, then it is possible to get a numerical value for the rector mixing angle, $\theta_{13}$, in very good agreement with the last experimental data, including the results of the experiments Daya Bay and RENO. We also show the branching ratios of some selected flavour changing neutral currents (FCNC) process.
