It was found that $NN$ potential could influence the results of the quasi-bound state search in the $K^- d$ system, where the corresponding pole is situated close to the threshold. Three-body Faddeev-type calculations of the $\bar{K}NN - \pi \Sigma N$ system performed with a new model of nucleon-nucleon interaction predict the existence of the quasi-bound $K^- d$ state caused by strong interactions. Its binding energy is small ($1-2$ MeV), while the width is comparable with the width of the $K^- pp$ quasi-bound state ($40-60$ MeV).

强相互作用引起的$$\pmb {{ K^- d}}$$系统中的准束缚态

发现$NN$势能影响$K^-d$系统中准束缚态搜索的结果，其中对应的极点位于阈值附近。$\bar{K}NN - \pi \Sigma N$ 系统的三体 Faddeev 型计算采用新的核子-核子相互作用模型，预测了准束缚 $K^- d$ 状态的存在通过强相互作用。它的结合能很小（$1-2$ MeV），而宽度与$K^-pp$准束缚态的宽度（$40-60$ MeV）相当。
