Abstract
We show that non-Hermitian and nearest-neighbor-interacting perturbations to the Fritzsch textures of lepton and quark mass matrices can make both of them fit current experimental data very well. In particular, we obtain θ23â45° for the atmospheric neutrino mixing angle and predict θ13â3° to 6° for the smallest neutrino mixing angle when the perturbations in the lepton sector are at the 20% level. The same level of perturbations is required in the quark sector, where the Jarlskog invariant of CP violation is about 3.7Ã10â5. In comparison, the strength of leptonic CP violation is possible to reach about 1.5Ã10â2 in neutrino oscillations.
