Predicting quark and lepton masses and mixings

Albright, Carl H. · Barr, S. M.

Original · EN

A model is presented that fits the quark and lepton masses and mixings wherein five dimensionless parameters and a phase account for fifteen dimensionless observables. Among these are the Wolfenstein parameters ρ and η, the νₑ-νμ and νₑ-ντ mixing angles which are predicted to be small and comparable while the νμ-ντ mixing angle is predicted to be large. The model is based on supersymmetric SO(10) with the form of the mass matrices motivated by simplicity at the level of grand unification.
