Fermion Mixings in SU(9) Family Unification
Abstract
In an SU(9) model of gauged family unification, we propose an explanation for why angles observed in the lepton flavor ( PMNS) mixing matrix are significantly larger than those measured for any analagous quark flavor ( KM) mixing angle. It is directly related to a see-saw mechanism that we assume to be responsible for the generation of neutrino masses. Our model is more constrained and therefore even more predictive than a model previously proposed by Barr.
