利用KNN-π σ N耦合通道Faddeev方程研究了KNN三体共振。利用非物理黎曼面上解析连续的散射振幅研究了S矩阵的极点。结果发现了一个结合能和宽度分别为B= 76 MeV和γ = 54 MeV的奇异双重子系统的三体共振。
KNN three body resonance has been studied by KNN-pi Sigma N coupled channel Faddeev equation. The S-matrix pole has been investigated using the analytically continued scattering amplitude on the unphysical Riemann sheet. As a result we found a three-body resonance of strange dibaryon system with the binding energy and width B=76MeV and \Gamma=54MeV.
