The paper presents a first time attempt on a combined fit of the $K^{-}p$ low-energy data and the πΣ photoproduction mass spectra, performed without fixing the meson-baryon rescattering amplitudes to a specific $\pi \mathrm{\Sigma }-\overline{K}N$ coupled channels model obtained from fitting exclusively the $K^{-}p$ data. The formalism adopted to describe the photoproduction process is based on chiral perturbation theory and employs a limited number of free parameters. The achieved description of the photoproduction mass distributions is not quite satisfactory, leaving a room for improving the photo-kernel construction. Although the presented models tend to constrain the positions of the $\mathrm{\Lambda }(1405)$ poles it is difficult to draw any conclusions before accomplishing better data reproduction.

本文首次尝试将$K^{-}p$低能数据和π Σ 光产生质谱，在未将介子-重子重散射振幅固定到特定值的情况下进行$\pi \mathrm{\Sigma }-\stackrel{￣}{K}氮$通过专门拟合获得的耦合通道模型$K^{-}p$数据。用于描述照片制作过程的形式主义基于手性微扰理论并采用有限数量的自由参数。所实现的照片制作质量分布的描述不太令人满意，为改进照片内核结构留下了空间。尽管所提出的模型往往会限制$\mathrm{\Lambda }(1405）$在完成更好的数据再现之前很难得出任何结论。
