我们研究了与三极大轻子混合和产生质量层次相容的级联形式的费米子质量矩阵。平级联轻子矩阵暗示了混合角和质量特征值之间的参数无关关系。这一关系表明，大气中微子混合角接近极大值，另外两个角与中微子质量特征值无关。我们还讨论了级联矩阵的现象学方面；带电轻子的异味稀有衰变、热轻生和轻子CP违逆。基于风味对称和高维理论说明了级联可能的动力学起源。
We study fermion mass matrices of the cascade form which are compatible with the tribimaximal lepton mixing and generation mass hierarchy. The flat-cascade lepton matrices imply a parameter-independent relation among the mixing angles and mass eigenvalues. The relation has several indications that the atmospheric neutrino mixing angle is close to maximal and the other two angles have a correlation independently of neutrino mass eigenvalues. We also discuss phenomenological aspects of the cascade matrices; flavor-violating rare decays of charged leptons, thermal leptogenesis, and leptonic CP violation. Possible dynamical origins of the cascades are illustrated based on flavor symmetry and in higher-dimensional theory.
