AI 中文摘要
强子共振态本质上是动力学状态,其可观测性质由夸克模型构型与强子道之间的相互作用所支配。哈密顿有效场论为连接强子动力学与实验可观测量及格点QCD结果提供了一个实用框架。在本综述中,我们概述了哈密顿有效场论的无穷体积和有限体积表述,并考察了其在轻强子谱学和共振结构方面的应用。通过用实验散射数据和格点QCD谱约束同一哈密顿框架,哈密顿有效场论有助于区分那些对现有散射数据描述得同样好、但对裸态和多强子构型角色给出不同含义的各种方案。我们还回顾了哈密顿框架近期为处理更复杂动力学情形而发展的扩展。
英文摘要
Hadron resonances are intrinsically dynamical states whose observable properties are governed by the interplay between quark-model configurations and hadronic channels. Hamiltonian effective field theory provides a practical framework for connecting hadron dynamics with experimental observables and lattice QCD results. In this review, we outline the infinite- and finite-volume formulations of Hamiltonian effective field theory and survey its applications to light-hadron spectroscopy and resonance structure. By constraining the same Hamiltonian framework with experimental scattering data and lattice QCD spectra, Hamiltonian effective field theory can help distinguish among scenarios that describe the available scattering data comparably well but imply different roles for bare-state and multihadron configurations. We also review recent extensions of the Hamiltonian framework developed to address more complicated dynamical settings.
