• A flavor mixing matrix (FMM) characterized uniquely by four group parameters of the SU(2)×U(1) symmetry is applied to the investigation of experimental results for the lepton and quark sectors. Neutrino oscillation data are analyzed by assuming that the 1-3 component of the lepton FMM vanishes. With this assumption, the lepton FMM is expressed in terms of analytic functions depending effectively on two group parameters. It is confirmed that, while all group parameters of the lepton FMM have values of approximately the same order of magnitude, those of the quark FMM have very different values with hierarchical structures. We make a conjecture concerning the behavior of the lepton FMM with a small but non-vanishing 1-3 component.
