论文摘要
Jülich-Bonn Group的目标是对SU（3）手性有效野外理论中涉及奇怪Baryons（$λ$，$σ$，$σ$，$σ$，$σ$，$σ$，$σ$，$σ$，$σ$，$σ$，$σ$，$σ$，$σ$）的互动的广泛研究。在过去几年中，提供了成就和新发展的概述。所涵盖的主题是：1）$λn$系统的领先电荷对称破坏（CSB）交互的推导，并在对CSB效应的应用中的应用中，以$ a $ a $ = $ 4 $ $ $ $ $ $ $λ$ -HYPERNUCLEI。 2）在NLO上的$ξn$交互的更新结果，以及$ξ^ - p $相关函数的预测。 3）$λn$ - $σn$交互的扩展到近代到领先的顺序。
The Jülich-Bonn group aims at an extensive study of the baryon-baryon ($BB$) interaction involving strange baryons ($Λ$, $Σ$, $Ξ$) within SU(3) chiral effective field theory. An overview of achievements and new developments over the past few years is provided. The topics covered are: 1) Derivation of the leading charge-symmetry breaking (CSB) interaction for the $ΛN$ system and its application in a study of CSB effects in $A$=$4$ $Λ$-hypernuclei. 2) Updated results for the $ΞN$ interaction at NLO and predictions for $Ξ^- p$ correlation functions. 3) Extension of the $ΛN$-$ΣN$ interaction to next-to-next-to-leading order.
