On a Quasi-Bound State in the K-d System Caused by Strong Interactions

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 K ¯ N N - π Σ N system performed with a new model of nucleon-nucleon interactio...

Zusammenfassung: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 K ¯ N N - π Σ 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 - p p quasi-bound state (40–60 MeV).
