论文摘要
我们提出了一种形式主义，用于对$γp\ rightarrow k^{+}πς$ Photodroduction反应（$λ^{\ ast}（1405）$ resonance区域中的低能分析。特别是，详细讨论了由单位性，仪表不变性和手性扰动理论产生的约束。
We present a formalism for the low-energy analysis of the $γp\rightarrow K^{+}πΣ$ photoproduction reaction in the $Λ^{\ast}(1405)$ resonance region. In particular, the constraints arising from unitarity, gauge invariance and chiral perturbation theory are discussed in some detail.
