摘要：

It was found that N N 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 (K) over bar N N - 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).
