Abstract

The A4 model of leptons was proposed originally for nearly degenerate neutrino masses. With minimal modification, it is shown to accommodate as well the cases of normal hierarchy and inverted hierarchy. In all cases, this new model predicts sin2 2 thetaatm = 1 and tan2 thetasol = 0.5 for Ue3 = 0. It also predicts their deviations from 1 and 0.5 respectively for Ue3 not equal to zero.
