我们回顾了与介子、介子、D介子、B介子和核子物理有关的晶格结果，目的是使它们更容易被核物理界和粒子物理界所理解。更具体地说，我们报道了轻夸克质量的测定，零动量转移时半轻子跃迁中出现的形式因子，以及对CKM矩阵元素和它的衰变常数比及其结果的测定。此外，我们描述了在晶格上得到的一些低能常数和手征微扰理论的结果。我们回顾了中性介子混合参数的确定，以及在标准模型之外的物理理论中出现的额外的四个B参数。对于重夸克部分，我们给出了和的结果，以及暗色和底部介子和重子的衰变常数、形状因子和混合参数的结果。这些是与确定CKM矩阵元素和全局CKM么正三角形拟合最相关的重夸克量。我们回顾了强耦合常数晶格测定的研究现状。我们考虑了核子矩阵元，并回顾了轴向、标量和张量双耳的确定，包括矢量和味道对角线。最后，在这次审查中，我们增加了一个新的章节，审查确定比例尺的数量。
We review lattice results related to pion, kaon,D-meson,B-meson, and nucleon physics with the aim of making them easily accessible to the nuclear and particle physics communities. More specifically, we report on the determination of the light-quark masses, the form factorarising in the semileptonictransition at zero momentum transfer, as well as the decay constant ratioand its consequences for the CKM matrix elementsand. Furthermore, we describe the results obtained on the lattice for some of the low-energy constants ofandChiral Perturbation Theory. We review the determination of theparameter of neutral kaon mixing as well as the additional fourBparameters that arise in theories of physics beyond the Standard Model. For the heavy-quark sector, we provide results forandas well as those for the decay constants, form factors, and mixing parameters of charmed and bottom mesons and baryons. These are the heavy-quark quantities most relevant for the determination of CKM matrix elements and the global CKM unitarity-triangle fit. We review the status of lattice determinations of the strong coupling constant. We consider nucleon matrix elements, and review the determinations of the axial, scalar and tensor bilinears, both isovector and flavor diagonal. Finally, in this review we have added a new section reviewing determinations of scale-setting quantities.
