Quasi-degenerate neutrinos and tri-bi-maximal mixing

High Energy Physics - Phenomenology 2010-04-15 v1

Abstract

Assuming high-energy tri-bi-maximal mixing we study the radiative running of leptonic mixing angles and obtain limits on the high-energy scale from requiring consistency with the observed mixing. We construct a model in which a non-Abelian discrete family symmetry leads both to a quasi-degenerate neutrino mass spectrum and to near tri-bi-maximal mixing.
