Description
We consider the possibility to take into account the role of the discrete A(4) flavor group into a context of unification obtained through the SU(5) gauge symmetry.
Our attention is dedicated to the possibility to preserve the renormalizability of the entire theory avoiding the presence of higher order operators, without forsaking to the usual elegance trough which A(4) can sketch out the correct path of mixing in the leptonic sector, reproducing the tri-bimaximal hypothesis.
