论文摘要
我们构建了几类HADRONIC矩阵元素，并将它们与手性扰动理论中的低能量常数相关联，这些元素描述了锥形和KAON半衰减β衰变中的电磁效应。我们建议使用晶格QCD对它们进行计算，并认为这样的计算将对Precision Frontier的许多有趣的主题产生直接影响，包括$ | v_ {us} | $的杰出异常和顶级的Cabibbo-Kobobay-Kobayashi-Maskahi-Maskawa Matrix Matrix Unitarity。
We construct several classes of hadronic matrix elements and relate them to the low-energy constants in Chiral Perturbation Theory that describe the electromagnetic effects in the semileptonic beta decay of the pion and the kaon. We propose to calculate them using lattice QCD, and argue that such a calculation will make an immediate impact to a number of interesting topics at the precision frontier, including the outstanding anomalies in $|V_{us}|$ and the top-row Cabibbo-Kobayashi-Maskawa matrix unitarity.
