项目摘要
The aim of this work is to analyze the reactions K^-+d→π+A(Σ)+N,K^-+d→K^++Ξ+N and to get information on ΛΝ-ΣΝ and ΞΝ-ΛΛ-ΛΣ-ΣΣ interactions. In order to perform reliable analyses we lay special importance on the collaboration with the groups developing realistic 2-body interactions, like A.Ramos and E.Oset (K^^-N interaction), the Nijmegen group, and Kyoto-Niigata group (baryon-baryon interactions). Also, the development of relativistic treatment of these coupled systems is one of the main issues because the transition occurs to the system including small-mass pion.The K^^-N amplitude by Oset and Ramos is coupled to possible channels and reproduces various experimental data with a small number of parameter. We extend their amplitude to the off-energy-shell region in the collaboration with A.Ramos. Also we finish the preparation to incorporate the Nijmegen Extended Soft Core interaction (transferred to the p-space representation) and Kyoto-Niigata quark-cluster-model interaction (RGM kernels) to our analyses mention above.The relativistic treatment of 3-body systems is a serious issue. Often the Bete-Salpeter equation has been used, but we have extended the Bakamjian-Thomas formalism to the ΚΝΝ-πΣΝ-πΛΝ system, because the nonrelativistic ingredients (for example, a realistic deuteron wave function) are well combined with this formalism. We investigate the 3-body kinematics and the boost of 2-body interactions from c.m. frame to the general frame.As mentioned above we have not reached to the aim originally expected, but we have solved the essential problems for the present analyses.
本工作的目的是分析反应K^-+d→π+A(π)+N,K^-+d→K^++ π +N,并得到Λ N-π N和π N-ΛΛ-Λ π-π N相互作用的信息。为了进行可靠的分析,我们特别重视与发展现实的二体相互作用的小组的合作,如A.拉莫斯和E.奥塞特(K^^-N相互作用)、奈梅亨小组和京都-新潟小组(重子-重子相互作用)。Oset和拉莫斯的K^^-N振幅与可能的通道耦合,用少量的参数再现了各种实验数据。在与A. Ramos的合作中,我们将它们的振幅扩展到离能壳层区域。我们还完成了将Nijmegen扩展软核相互作用(转移到p空间表示)和Kyoto-Niigata夸克团模型相互作用(RGM核)引入到上述分析中的准备工作。通常使用贝特-萨尔彼得方程,但我们将巴卡姆坚-托马斯形式主义扩展到了π N N-πΛ N系统,因为非相对论成分(例如,一个现实的氘核波函数)与这种形式主义很好地结合在一起。我们研究了3-体运动学和2-体相互作用的c.m.虽然没有达到预期的目的,但解决了本文分析的基本问题。
