Predictive flavor symmetries of the neutrino mass matrix

Abstract

Here we propose an A(4) flavor symmetry model that implies a lower bound on the neutrinoless double beta decay rate, corresponding to an effective mass parameter M-ee greater than or similar to 0.03 eV, and a direct correlation between the expected magnitude of CP violation in neutrino oscillations and the value of sin^2 Θ(13), as well as a nearly maximal CP phase δ.
