Abstract

We study how observables of the neutrino mixing matrix can link up with those in the quark sector. The deviation from the bimaximal flavor mixing is parametrized using a 3\ifmmode×\else\texttimes\fi3 unitary matrix. The neutrino mixings are investigated supposing this unitary matrix to be hierarchical like the quark mixing matrix. We obtain the remarkable prediction |U_e3|>~0.03 from the experimentally allowed range tan²\ensuremathθ_sol=0.24--0.89. The CP violation in neutrino oscillations is expected to be very small.
