标题： Baryon-baryon interactions in free space and baryonic medium

摘要： 我们研究八重态重子在相对论介子交换方法中的相互作用，该方法将自由空间和介质中相互作用与有限（超）核中的相互作用联系起来。 给出了包括相对论T矩阵和G矩阵以及G矩阵在密度依赖相对论强子场理论（DDRH）中映射到密度依赖顶点泛函的模型简图。 从中等质量超核的新光谱数据中，我们提取了单粒子谱包括自旋-轨道分裂。 对$\Lambda\omega$矢量和张量顶点以及$\Lambda\sigma$顶点的提取显示出SU(3)对称性的强烈破坏。 显示英文摘要

摘要： We study the interactions of the octet baryons in a relativistic meson exchange approach connecting free-space and in-medium interactions with those in finite (hyper)nuclei. A short sketch of the model including the relativistic T- and G-matrix and the mapping of the G-matrix onto density dependent vertex functionals in the density dependent relativistic hadron field theory (DDRH) is given. From new spectroscopic data on medium mass hypernuclei we extract the single particle spectrum including spin-orbit splitting. An extraction of the $\Lambda\omega$ vector- and tensor vertex as well as the $\Lambda\sigma$-vertex shows a strong breaking of SU(3) symmetry.
