我们分析了最近提出的非对称质量矩阵模型的轻子扇区。我们的模型基于一个扩展的味2{r_reversible}3对称性和一个相位，给出了夸克和轻子具有相同纹理形式的统一描述。通过研究可能的质量分配类型，我们发现该模型可以导致与实验值一致的大轻子混合。我们还发现，该模型预测轻子混合矩阵元平方的值很小，为1.3 × 10 {sup-10}| U{sub 13}|{sup 2}。还预言了轻子混合矩阵中的CP破坏相和无中微子双β衰变中平均中微子质量的抑制。
We analyze the lepton sector of a recently proposed nonsymmetric mass matrix model. Our model gives a unified description of quark and lepton with the same texture form based on an extended flavor 2{r_reversible}3 symmetry with a phase. By investigating possible types of assignment for masses, we find that the model can lead to large lepton mixings which are consistent with experimental values. We also find that the model predicts a very small value, 1.3x10{sup -10}, for the lepton mixing matrix element square |U{sub 13}|{sup 2}. The CP-violating phases in the lepton mixing matrix and a suppression of the averaged neutrino mass in the neutrinoless double beta decay also are predicted.
