Abstract: (IOP)
The measurement of the last neutrino mixing angle θ13 giving a a non zero value has established a new challenge for the theoretical understanding of the lepton mixing. The use of discrete symmetries to successfully explain that mixing is still possible. As an example, we have modified the so called Babu-Ma-Valle model in such a way that we account for the current neutrino mixing values at 3σ. In particular, we have obtained not only compatibility with a θ13 ≠ 0, but also a non maximal θ23.
