标题： Chiral model for $\bar{K}N$ interactions and its pole content

摘要： 我们使用手征激励的有效介子-重子势来描述低能$\bar{K}N$数据，包括奇异氢的特性。 我们的结果与其他基于T矩阵逆元的单位性和色散关系的方法进行比较。 我们证明，随着模型参数变化，由模型生成的极点的运动可以作为工具，以获得对强耦合$\pi\Sigma$-$\bar{K}N$系统动力学的额外洞察。 显示英文摘要

摘要： We use chirally motivated effective meson-baryon potentials to describe the low energy $\bar{K}N$ data including the characteristics of kaonic hydrogen. Our results are examined in comparison with other approaches based on the unitarity and dispersion relation for the inverse of the T-matrix. We demonstrate that the movements of the poles generated by the model upon varying the model parameters can serve as a tool to get additional insights on the dynamics of the strongly coupled $\pi\Sigma$-$\bar{K}N$ system.
