论文摘要
$ i = \ frac {1} {2} $，$ j^π= \ frac {1} {2}^{+} $状态的三体计算执行了$ k \ bar {k} n $ system的状态。使用可分离电位来实现FADDEEV方程中的两体相互作用，研究了$ k \ bar {k} n $三体系统的不同反应过程。在此方法中，提取了$πς{k} $和$πη{n} $质量光谱。使用了基于现象学和手性SU（3）方法的不同类型的$ \ bar {k} n-πς$电势，并研究了质谱对$ \ bar {k} n $交互模型的依赖性。结果表明，$πς{k} $和$πη{n} $质谱可能是研究$ n^{\ star} $共振的属性的有用工具。
Three-body calculations of $I=\frac{1}{2}$, $J^π=\frac{1}{2}^{+}$ state of $K\bar{K}N$ system were performed. Using separable potentials for two-body interactions in the Faddeev equation, different reaction process for $K\bar{K}N$ three-body system were studied. Within this method, the $πΣ{K}$ and $πη{N}$ mass spectra were extracted. Different types of $\bar{K}N-πΣ$ potentials based on phenomenological and chiral SU(3) approach were used and the dependence of the mass spectra to the $\bar{K}N$ model of interaction were studied. It was shown that the $πΣ{K}$ and $πη{N}$ mass spectra could be a useful tool to study the properties of the $N^{\star}$ resonance.
