标题： Hadron spectroscopy and few-body dynamics from lattice QCD

摘要： 尽管量子色动力学（QCD）已被确立为强相互作用的理论，并且自那时以来取得了许多成功，但在介子物理的理解方面仍存在重大挑战。 缺乏对如何从定义QCD的夸克和胶子自由度中出现的已观察到的介子的完全理解，代表了将理论与实验联系起来的一个真正挑战。 特别是，介子的丰富谱标志出我们理解中的一个显著空白，因为目前没有任何模型能够解释所有已观察到的介子，而QCD本身仅被用于研究整个谱系的一个小部分。 直接使用QCD的主要障碍是该理论在低能下的非微扰性质，这需要像格点QCD这样的方法。 在这里，回顾了介子的谱及其与少体动力学的关系，重点是通过格点QCD研究它们的最新方法。 显示英文摘要

摘要： Despite quantum chromodynamics (QCD) being established as the theory of the strong interaction and its many successes since then, significant challenges in our understanding of hadron physics remain. The lack of a full understanding for how the observed hadrons arise from the quark and gluon degrees of freedom which define QCD represents a real challenge in connecting the theory to experiment. In particular, the rich spectrum of hadrons marks a significant gap in our understanding, as no model can currently explain all observed hadrons and QCD itself has only been used to study a small subset of the full spectrum. The significant hurdle for using QCD directly is due to the non-perturbative nature of the theory at low energies, requiring methods like lattice QCD. Here, the spectrum of hadrons and how it relates to few-body dynamics is reviewed, with a focus on state-of-the-art methods for their study through lattice QCD.
