The Faddeev equations for the \(\varXi NN\) bound-state problem are solved where the three \(S=-2\) baryon–baryon interactions of Jülich-Bonn-München chiral EFT, HAL QCD and Nijmegen ESC08c are used. The T-matrix \(T_{\varXi N, \varXi N}\) obtained within the original \(\varLambda \varLambda -\varXi N-\varSigma \varSigma /\varXi N-\varLambda \varSigma -\varSigma \varSigma \) coupled-channel framework is employed as an input to the equations. We found no bound state for Jülich-Bonn-München chiral EFT and HAL QCD but ESC08c generates a bound state with the total isospin and spin-parity \((T,J^{\pi })=(1/2, 3/2^+)\) where the decays into \(\varLambda \varLambda N\) are suppressed.

在使用Jülich-Bonn-München 手性 EFT、HAL QCD 和 Nijmegen ESC08c的三个\(S=-2\)重子-重子相互作用的情况下，解决了\(\varXi NN\)束缚态问题的 Faddeev 方程。原始\(\varLambda \varLambda -\varXi N-\varSigma \varSigma /\varXi N-\varLambda \varSigma -\varSigma \ )内得到的T-矩阵\(T_{\varXi N, \varXi N}\) varSigma \)耦合通道框架用作方程的输入。我们没有发现 Jülich-Bonn-München 手性 EFT 和 HAL QCD 的束缚态，但 ESC08c 生成了一个具有总同位旋和自旋奇偶性的束缚态\((T,J^{\pi })=(1/2, 3/ 2^+)\)其中衰减为\(\varLambda \varLambda N\) 被压制。
