Abstract

A partial-wave analysis (PWA) for the photoproduction of pseudoscalar mesons on a nucleon using truncation in total angular momentum j is discussed. A formalism is described that can be used for investigating discrete ambiguities. Considerable attention is devoted to the connection of this type of PWA with that based on the truncation in orbital angular momentum l.

具有截断总角动量的伪谱介子光生成的部分波分析

讨论了利用总角动量 j 截断法对核子上的伪谱介子进行光生成的部分波分析（PWA）。描述了一种可用于研究离散模糊性的形式主义。研究还特别关注了这种 PWA 与基于轨道角动量 l 的截断的 PWA 之间的联系。
