On Bimaximal Neutrino Mixing and GUT's
arXiv:1504.05514
Abstract
We briefly discuss the present status of models of neutrino mixing. Among the existing viable options we review the virtues of Bimaximal Mixing (that could be implemented by an discrete symmetry), corrected by terms arising from the charged lepton mass diagonalization. In particular in a GUT formulation the property of quark lepton "weak" complementarity can be naturally realized. We discuss in some detail two new versions of particular GUT models, one based on and one on and the associated phenomenology. We compare these approaches based on symmetry to models based on chance, like Anarchy or .
