Abstract

We explore some important implications of the KamLAND measurment on the lepton flavor mixing matrix V and the neutrino mass matrix M. The model-independent constraints on nine matrix elements of V are obtained to a reasonable degree of accuracy. We find that nine two-zero textures of M are compatible with current experimental data, but two of them are only marginally allowed. Instructive predictions are given for the absolute neutrino masses, Majorana phases of CP violation, effective masses of the tritium beta decay, and neutrinoless double beta decay.
