Coupled-channel dynamics for scattering and production processes in partial-wave amplitudes is discussed from a perspective that emphasizes unitarity and analyticity. We elaborate on several methods that have driven to important results in hadron physics, either by themselves or in conjunction with effective field theory. We also develop and compare with the use of the Lippmann-Schwinger equation in near-threshold scattering. The final(initial)-state interactions are discussed in detail for the elastic and coupled-channel case. Emphasis has been put in the derivation and discussion of the methods presented, with some applications examined as important examples of their usage.

强子-强子散射中的耦合通道方法

从强调单一性和分析性的角度讨论了分波振幅中散射和产生过程的耦合通道动力学。我们详细阐述了几种在强子物理学中取得重要成果的方法，无论是单独的还是与有效的场论相结合的。我们还开发并比较了在近阈值散射中使用 Lippmann-Schwinger 方程。针对弹性和耦合通道情况详细讨论了最终（初始）状态相互作用。重点放在了对所介绍方法的推导和讨论上，并检查了一些应用程序作为其使用的重要示例。
