利用jjlich - bonn - m<e:1> nchen手性EFT、HAL QCD和Nijmegen ESC08c的三重子-重子相互作用求解了束缚态问题的Faddeev方程。在原始耦合通道框架内得到的t矩阵被用作方程的输入。我们发现j<s:1> lich- bonn - mnchen手性EFT和HAL QCD没有束缚态，但ESC08c产生了一个具有总同位旋和自旋奇偶的束缚态，其中衰变被抑制。
The Faddeev equations for thebound-state problem are solved where the threebaryon–baryon interactions of Jülich-Bonn-München chiral EFT, HAL QCD and Nijmegen ESC08c are used. TheT-matrixobtained within the originalcoupled-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-paritywhere the decays intoare suppressed.
