论文摘要
在晶格QCD中，多 - 戴隆动力学的第一原理计算是一个至关重要的目标。在开发，实施和应用理论工具中取得了重大进展，这些工具将有限体积数量连接到其无限体积同行。在这里，我回顾了一些有关有限体积多粒子量的最新理论发展和数值结果。这些结果包括$nπ$散射，最大同胞素的两个和三个介子的系统，玩具模型中的三体共振以及多核电系统有限量的有效理论的提出。
First-principles calculations of multi-hadron dynamics are a crucial goal in lattice QCD. Significant progress has been achieved in developing, implementing, and applying theoretical tools that connect finite-volume quantities to their infinite-volume counterparts. Here, I review some recent theoretical developments and numerical results regarding multi-particle quantities in a finite volume. These results include $Nπ$ scattering, systems of two and three mesons at maximal isospin, three-body resonances in a toy model, and the formulation of effective theories in finite volume for multi-nucleon systems.
