对低位共振强相互作用物理的描述超出了微扰QCD的有效范围。手征有效场理论（EFT）已被开发来解决这个问题。分波动力学是一种系统性的工具，可以用来解释基本的物理现象，并揭示这些共振的性质。它是非常强大的，有助于我们理解的非微扰制度，特别是当色散技术同时使用。近年来，LHCb、贝儿和BESIII等实验合作组报道了大量奇异/普通强子。本文综述了部分波动力学结合手征EFT和色散关系在相关课题上的应用进展，重点介绍了ππ、πK、πN和K-N散射。
The description of strong interaction physics of low-lying resonances is out of the valid range of perturbative QCD. Chiral effective field theories (EFTs) 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 EFTs and dispersion relations, on related topics, with emphasis on ππ, πK, πN and K̄N scatterings.
