We review lattice results related to pion, kaon, - and -meson physics with the aim of making them easily accessible to the particle-physics community. More specifically, we report on the determination of the light-quark masses, the form factor [Formula: see text], arising in the semileptonic [Formula: see text] transition at zero momentum transfer, as well as the decay constant ratio [Formula: see text] and its consequences for the CKM matrix elements [Formula: see text] and [Formula: see text]. Furthermore, we describe the results obtained on the lattice for some of the low-energy constants of [Formula: see text] and [Formula: see text] Chiral Perturbation Theory. We review the determination of the [Formula: see text] parameter of neutral kaon mixing as well as the additional four parameters that arise in theories of physics beyond the Standard Model. The latter quantities are an addition compared to the previous review. For the heavy-quark sector, we provide results for [Formula: see text] and [Formula: see text] (also new compared to the previous review), as well as those for - and -meson-decay constants, form factors, and mixing parameters. These are the heavy-quark quantities most relevant for the determination of CKM matrix elements and the global CKM unitarity-triangle fit. Finally, we review the status of lattice determinations of the strong coupling constant [Formula: see text].
我们回顾与π介子、K介子、η介子和η'介子物理学相关的晶格结果，目的是使粒子物理学界能够轻松获取这些结果。更具体地说，我们报告了轻夸克质量的确定、在零动量转移的半轻子衰变过程中出现的形状因子，以及衰变常数比及其对CKM矩阵元的影响。此外，我们描述了在晶格上获得的关于手征微扰理论中一些低能常数的结果。我们回顾了中性K介子混合参数的确定以及超出标准模型的物理学理论中出现的另外四个参数。与之前的综述相比，后一组量是新增的内容。对于重夸克部分，我们给出了（同样与之前的综述相比是新的）以及η介子和η'介子衰变常数、形状因子和混合参数的结果。这些是确定CKM矩阵元和全球CKM幺正三角形拟合最相关的重夸克量。最后，我们回顾了晶格确定强耦合常数的现状。
