Hadronic matrix element in QCD including isospin-breaking effects

该项目旨在计算晶格QCD中轻介子衰变率的强子修正，包括同位旋破坏效应，目的是改进CKM矩阵统一性的测试。约束CKM矩阵是探测新物理信号并对其进行表征的关键。这项工作直接与实验结果相结合，可以提取与过程无关的值（CKM矩阵元素），可用于测试标准模型的极限。

The project aims to calculate hadronic corrections to light meson decay rates in lattice QCD including isospin-breaking effects with the aim of improving tests of the unitarity of the CKM matrix. Constraining the CKM matrix is key to detecting signals of new physics and characterising them. This work directly combined with experimental results allows for the extraction of process independent values (CKM matrix elements) which can be used to test the limits of the Standard Model.
