论文摘要
对低洼共振的强相互作用物理学的描述超出了扰动QCD的有效范围。已经开发了手性有效的现场理论来解决这个问题。部分波动力学是解码基本物理并揭示这些共振的特性的系统工具。它对我们对非扰动制度的理解非常有力和有帮助，尤其是当同时使用分散技术时。最近，实验合作报道了大量异国/普通的哈登子，例如LHCB，Belle和Besiii等。在这篇评论中，我们总结了局部波动力学应用的最新进展，并在相关主题上结合了手性有效的现场理论和分散关系，重点是$ππ$，$πk$，$πn$，$πn$和$ \ bar {k} k} n $ scastings。
The description of strong interaction physics of low-lying resonances is out of the valid range of perturbative QCD. Chiral effective field theories have been developed to tackle the issue. Partial wave dynamics is the systematic tool to decode the underlying physics and reveal the properties of those resonances. It is extremely powerful and helpful for our understanding of the non-perturbative regime, especially when dispersion techniques are utilized simultaneously. Recently, plenty of exotic/ordinary hadrons have been reported by experiment collaborations, e.g. LHCb, Belle, and BESIII, etc.. In this review, we summarize the recent progress on the applications of partial wave dynamics combined with chiral effective field theories and dispersion relations, on related topics, with emphasis on $ππ$, $πK$, $πN$ and $\bar{K}N$ scatterings.
