Predictive flavor symmetries of the neutrino mass matrix

Abstract

Here we propose an A4 flavor symmetry model that implies a lower bound on the neutrinoless double beta decay rate, corresponding to an effective mass parameter Mee 0.03eV, and a direct correlation between the expected magnitude of CP violation in neutrino oscillations and the value of sin 2θ13, as well as a nearly maximal CP phase δ. © 2007 The American Physical Society.
