  • We reanalyze Majorana neutrino mass matrices with two texture zeros, by searching for viable hybrid textures in which the non-zero matrix elements of have simple ratios. Referring to the classification scheme of Frampton, Glashow and Marfatia, we find that the mass matrix denoted by A1 allows the ratios and . There are analogous ratios for texture A2. With these two hybrid textures, one obtains, for instance, good agreement with the data if one computes the three mixing angles in terms of the… CONTINUE READING
