摘要

In the original 2004 paper which first derived tribimaximal mixing in the context of A(4), i.e., the non-Abelian finite symmetry group of the tetrahedron, as its simplest application, it was also pointed out how theta(13) not equal 0 may be accommodated. On the strength of the new T2K result that 0.03(0.04) <= sin(2)2 theta(13) <= 0.28(0.34) for delta(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).
