计算了标准模型有效场论的6维算符的59×59单圈反常维矩阵的完全y2和y4项，其中y是一般的Yukawa耦合.这些项与以前工作中计算的依赖于标准模型希格斯自耦合λ，λ的阶数为λ2和λy 2的项一起，得到了消失规范耦合极限下的完整的单圈反常维矩阵。汤川遥菜的贡献导致了标准模型有效理论的不同算符部分的不平凡的味道混合。
We calculate the complete order y 2 and y 4 terms of the 59× 59 one-loop anomalous dimension matrix for the dimension-six operators of the Standard Model effective field theory, where y is a generic Yukawa coupling. These terms, together with the terms of order λ, λ 2 and λy 2 depending on the Standard Model Higgs self-coupling λ which were calculated in a previous work, yield the complete one-loop anomalous dimension matrix in the limit of vanishing gauge couplings. The Yukawa contributions result in non-trivial flavor mixing in the various operator sectors of the Standard Model effective theory.
