我们提出了一个基于两种阿贝尔味对称的夸克和轻子质量矩阵模型。其中一个假设是在普朗克尺度附近的高能区被打破。它用于夸克和带电轻子扇区的Froggatt-Nielsen机制。另一个保持不间断的多TeV区域。中微子和高金诺的混合，包括新阿贝尔对称性的混合，产生非零质量和中微子之间的混合。中微子振荡的双峰方案可以与适当的质量和夸克扇区中的CKM混合一起实现。FCNC对这种依赖于味道的阿贝尔对称性的约束似乎是回避的。
We propose a model for the mass matrices of quarks and leptons based on two Abelian flavor symmetries. One is assumed to be broken at a high energy region near the Planck scale. It is used for the Froggatt-Nielsen mechanism in both quark and charged lepton sectors. Another one remains unbroken to a multi-TeV region. The mixings among neutrinos and gauginos including the one of the new Abelian symmetry generate non-zero masses and mixings among neutrinos. A bi-maximal scheme for the neutrino oscillation can be realized together with suitable masses and CKM-mixings in the quark sector. FCNC constraints on this flavor dependent Abelian symmetry seems to be evaded.
