Interactions of two-baryon systems with strangeness

将上田、Riewe和Green关于核子相互作用的单玻色子交换势(OBEP)推广到超子-核子相互作用。考虑了赝标量、标量和矢量SU(3)非重态介子。它们遵循SU(3)不变性。此外，还介绍了SU(3)破坏介子。成功的结果分为以下两类：I和II。对于σ，κ，Ω耦合系统，在SU(3)破坏介子ΛΝ-ΣΝ和P的情况下，导出了一个OBEP。这个势正确地描述了关于这个系统的散射和反应的所有可用数据。超三电子的结合能被精确地复制了。本文明确了ΣNI=3/2^3S_1分量与Nijmegen 97F势的一个区别点，并提出了实验检验它的方法。在SU(3)破坏介子σ的情况下，还导出了SU(3)破坏介子的ΞΝ和ΞΞ系统的OBEP。ΞΝOBEP被应用于Ξ^--原子核束缚态。只有耦合常数g_t；ΞΞσ&gt；是可调节和确定的，以便重现Ξ^-^&lt；12&gt；C束缚态的结合能。我们预测了ΞΝ和ΞΞ系统的散射态和束缚态，特别是Ξ-^&lt；11&gt；Β束缚态，与实验信号一致。

The One-Boson-Exchange-Potential (OBEP) due to Ueda, Riewe and Green for nucleonnucleon interaction is extended to ones for hyperon-nucleon interactions. The pseudoscalar, scalar and vector SU (3) nonet mesons are taken into account. They follow the SU (3) invariance. Additionally SU (3) violating mesons are introduced. Successful results are classified into the following I and II.I An OBEP is derived with the SU (3) violating mesons, σ, κ, Ω and P, for ΛΝ-ΣΝ coupled system. The potential describes correctly all the available data on the scatterings and reactions of this system. The binding energy of the hypertriton is exactly reproduced. A discriminating point of this potential from Nijmegen 97f one is made clear about the ΣNI=3/2 ^3S_1 component and how to examine it experimentally is suggested.II OBEP's for ΞΝ and ΞΞ systems are also derived witlt the SU (3) violating meson, σ. The ΞΝ OBEP is applied to Ξ^--nucleus bound states. Only the coupliung constant g_<ΞΞσ> is adjustable and determined so as to reproduce the binding energy of Ξ^--^<12>C bound state. We predict the scattering and bound states for ΞΝ and ΞΞ systems and in particular a Ξ-^<11>Β bound state in agreement with an experimental signal.
