Nonzero θ_{13} for Neutrino Mixing in the Context of A_{4} Symmetry
Abstract
In the original 2004 paper which first derived tribimaximal mixing in the context of A_{4}, i.e., the nonAbelian finite symmetry group of the tetrahedron, as its simplest application, it was also pointed out how θ_{13}≠0 may be accommodated. On the strength of the new T2K result that 0.03(0.04)≤sin^{2}2θ_{13}≤0.28(0.34) for δ_{CP}=0 and normal (inverted) neutrino mass hierarchy, we perform a more detailed analysis of how this original idea may be realized in the context of A_{4}.
