论文摘要
发现$ nn $的电位可能会影响$ k^ - d $系统中准结合状态搜索的结果,在$ k^ - d $系统中,相应的极点位于阈值附近。 $ \ bar {k} nn-πσn$系统的三体Faddeev-type计算以核子 - 核子相互作用的新模型执行,预测了由QUASI结合的$ k^ - d $状态的存在,这是由强相互作用引起的。它的绑定能量很小($ 1-2 $ MEV),而宽度可与$ k^ - pp $ quasi-bound Bound State($ 40-60 $ MEV)相当。
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 $\bar{K}NN - πΣN$ 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).
