Models of Neutrino Masses and Mixings: a Progress Report
arXiv:0705.0860
Abstract
We present some recent developments on model building for neutrino masses and mixings. In particular, we review tri-bimaximal neutrino mixing derived from discrete groups, notably A4. We discuss the problems encountered with extending the symmetry to the quark sector and with Grand Unification.
