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.

该项目旨在计算晶格QCD中轻介子衰变率的强子修正，包括同位旋破缺效应，目的是改进CKM矩阵的幺正性测试。约束CKM矩阵是检测新物理信号并表征它们的关键。这项工作直接结合实验结果允许提取过程独立的值（CKM矩阵元素），可用于测试标准模型的限制。
