我们研究了奇异双重子与三体系统共振的特征如何在物理真实的能量轴上表现为散射振幅和可观测量。所谓的点法是用来处理对数奇异性，出现在解决Alt-Grassberger-Sandhas方程的真实的散射能量。通过采用两种不同的两体子系统模型，这两种模型同样很好地再现了现有的数据，但给出了相当不同的共振极结构，我们还研究了奇异双重子产生反应是否可以用于解开的性质。
We examine how the signature of the strange-dibaryon resonances withandshows up in scattering amplitudes and observables of the three-body-system on the physical real energy axis. The so-called point method is applied to handle logarithmic singularities that appear in solving the Alt-Grassberger-Sandhas equations for the real scattering energies. By taking two different kinds of models for the two-body-subsystem, both of which reproduce the available data equally well but give quite a different resonance-pole structure for, we also investigate whether the strange-dibaryon production reactions can be used for disentangling the nature of.
