标题： A new ansatz for quark and lepton mass matrices

摘要： 在超对称大统一理论的背景下，提出了一种新的关于夸克和轻子质量矩阵的假设。 描述费米子质量和混合的13个参数仅用6个自由参数来确定，允许7个可检验的预测。 $V_{us}$、$V_{cb}$、$V_{ub}$、$m_u$、$m_d$、$m_s$和$m_b$的值随后作为3个带电轻子质量$m_c$、$m_t$和$\tan \beta$以及希格斯真空期望值的比值的函数进行预测。 特别是Cabibbo角和$m_s/m_d$是根据轻子质量确定的。 所有预测与实验结果高度一致。 显示英文摘要

摘要： A new ansatz for quark and lepton mass matrices is proposed in the context of supersymmetric grand unified theories. The 13 parameters describing fermion masses and mixings are determined in terms of only 6 free parameters, allowing 7 testable predictions. The values of $V_{us}$, $V_{cb}$, $V_{ub}$, $m_u$, $m_d$, $m_s$, and $m_b$ are then predicted as a function of the 3 charged lepton masses, $m_c$, $m_t$, and $\tan \beta$, the ratio of Higgs vacuum expectation values. In particular the Cabibbo angle and $m_s/m_d$ are determined in terms of only lepton masses. All predictions are in very good agreement with experiments.
