夸克的味混合和一种新的织构

Flavor Mixing of Quarks and a New Texture

Harald Fritzsch

摘要:

我们讨论了一种新的夸克质量矩阵,它具有特定的纹理零点。夸克的三个味混合角是夸克质量的函数,可以计算。以下CKM矩阵元素之间的比率由夸克质量的比率给出:|Vtd/Vts| ' q md /ms和|Vub/Vcb|' p mu/mc。我们还可以计算两个CKM矩阵元素:|Vcb|“|Vts|”2(ms/mb)。这种关系以及|Vtd/Vts| QMD/MS与实验数据符合良好。关系有问题|Vub/Vcb| p μ/mc,可能是由于对夸克质量μ和m的错误估计

英文摘要:

We discuss a new mass matrix with specific texture zeros for the quarks. The three flavor mixing angles for the quarks are functions of the quark masses and can be calculated. The following ratios among CKM matrix elements are given by ratios of quark masses: |Vtd/Vts| ' q md /ms and |Vub/Vcb| ' p mu/mc . Also we can calculate two CKM matrix elements: |Vcb| ' |Vts| ' 2 (ms/mb ). This relation as well as the relation |Vtd/Vts| ' q md /ms are in good agreement with the experimental data. There is a problem with the relation |Vub/Vcb| ' p mu/mc , probably due to wrong estimates of the quark masses mu and m
