论文摘要
Fritzsch-Xing矩阵是特定类别的纹理4零赫尔米尼亚夸克质量矩阵，已知在适应夸克混合数据方面成功。在目前的工作中，结果表明，与通常的两个相位参数不同，这些纹理的4零矩阵不仅与最新的实验性夸克混合数据一致，而且还可以预测与最近的全球分析协议的CP违规参数，$ J $和相应的相位$δ$。我们还表明，质量矩阵元素没有表现出强大的层次结构，并且在上下扇区的某些质量矩阵元素之间存在很强的相关性。 $δ$以及小夸克质量的精确度量可能会进一步限制矩阵的相结构。
Fritzsch-Xing matrices are a particular class of texture 4 zero hermitian quark mass matrices, known to be successful in accommodating the quark mixing data. In the present work, it is shown that these texture 4-zero matrices with only one phase parameter, unlike the usually considered two phase parameters, are not only consistent with the latest experimental quark mixing data, but also predict the CP violation parameters, $J$ and corresponding phase $δ$, in agreement with the recent global analyses. We also show that the mass matrix elements do not exhibit a strong hierarchy and there is a strong correlation between some of the mass matrix elements of up and down sector. A precision measurement of $δ$ as well as small quark masses would have the potential to constrain the phase structure of the matrices further.
