标题： Relation between quark masses and weak mixings

摘要： 简单变换公式在费米子矩阵和可观测量之间得到，以及夸克矩阵的数值，在一个特定的弱基下，其中一个夸克矩阵对角化，另一个具有消失的元素1-1、1-3和3-1，并且只有元素2-2是复数。当我们选择$M_u$对角化时，$M_d$显示出有趣的数值性质，这表明可以用四个参数来描述它，这意味着$V_{us}\simeq \sqrt{m_d/m_s}$、$V_{cb}\simeq (3/\sqrt{5})(m_s/m_b)$和$V_{ub}\simeq (1/\sqrt{5})(\sqrt{m_d m_s}/m_b)$。添加了一些关于质量混合关系的评论。 显示英文摘要

摘要： Simple transformation formulas between fermion matrices and observables, and numerical values of quark matrices, are obtained on a particular weak basis with one quark matrix diagonal and the other with vanishing elements 1-1, 1-3 and 3-1, and with only the element 2-2 complex. When we choose $M_u$ diagonal, then $M_d$ shows intriguing numerical properties which suggest a four parameter description of it, which implies $V_{us}\simeq \sqrt{m_d/m_s}$, $V_{cb}\simeq (3/\sqrt{5})(m_s/m_b)$ and $V_{ub}\simeq (1/\sqrt{5})(\sqrt{m_d m_s}/m_b)$. Few comments on mass-mixing relations are added.
