通过引入夸克和荷电轻子质量矩阵的2{r_reversible}3反对称部分，探索了一种2{r_reversible}3对称性破缺的普适质量矩阵模型的唯象方法.我们提出了明确的纹理分量的质量矩阵，这是一致的所有中微子振荡实验和夸克混合数据。夸克和轻子的质量矩阵具有共同的结构，而轻子大混合和小夸克混合由于相位因子的不同而没有进行微调。该模型预测轻子混合矩阵元平方U{sub 13}{sup 2}的值为2.4 × 10 {sup-3}，无中微子双β衰变中出现的平均中微子质量也为=（0.89-1.4）× 10 {sup-4} eV。
A phenomenological approach for the universal mass matrix model with a broken flavor 2{r_reversible}3 symmetry is explored by introducing the 2{r_reversible}3 antisymmetric parts of mass matrices for quarks and charged leptons. We present explicit texture components of the mass matrices, which are consistent with all the neutrino oscillation experiments and quark mixing data. The mass matrices have a common structure for quarks and leptons, while the large lepton mixings and the small quark mixings are derived with no fine-tuning due to the difference of the phase factors. The model predicts a value 2.4x10{sup -3} for the lepton mixing matrix element square U{sub 13}{sup 2}, and also =(0.89-1.4)x10{sup -4} eV for the averaged neutrino mass which appears in the neutrinoless double beta decay.
