Abstract
Motivated by the recent data from T2K and MINOS, which show the evidence ofa relatively large theta13 at 3 sigma level, we study the phenomenologicalimplications of the bimaximal mixing (BM), the tri-bimaximal mixing (TBM),and the democratic mixing (DC) matrices with some modifications. Using suchmixing matrices and assuming texture one-zero in the neutrino mass matriceswe have shown whether such mixing matrices satisfy normal or inverted masshierarchy, or phenomenologically viable or not. We have scrutinizedfurther implications of Democratic mixing matrix, motivated by its successin naturally accommodating the nonzero reactor mixing angle theta13. Wehave also explored the possibility of determining the mass hierarchy,octant of the atmospheric mixing angle theta23, and the CP violationdiscovery potential in the current and upcoming long-baseline experimentsT2K, NOvA and LBNE (DUNE).
