论文摘要
在Kaon核系统中，反kaon和核子之间的强烈相互作用是各种有趣现象的起源。特别是，Isospin $ i = 0 $通道中的相互作用足以产生一个准结合状态，即$λ（1405）$共振，低于$ \ bar {k} n $阈值。基于这张图片，可以预期$ \ bar {k} n $相互作用还会在Kaon核系统中产生准结合状态，有时称为Kaonic Nuclei。同时，$ \ bar {k} n $ quasi结合的$λ（1405）$的图片也与对强子光谱中的黑辐分子的讨论有关。这里概述了针对Kaon-Nucleon和Kaon核系统开发的理论研究。我们从对$λ（1405）$共振的现代理解开始。然后，我们讨论$ \ bar {k} n $相互作用和几个小核核的各个方面。从核多体物理学的角度检查了较重的kaon核系统，重点是核物质中抗ka的性质。还讨论了相关主题，例如$ k^{ - } p $动量相关性在高能量碰撞中的功能和关于花原子的研究。
The strong interaction between an antikaon and a nucleon is at the origin of various interesting phenomena in kaon-nuclear systems. In particular, the interaction in the isospin $I=0$ channel is sufficiently attractive to generate a quasi-bound state, the $Λ(1405)$ resonance, below the $\bar{K}N$ threshold. Based on this picture, it may be expected that the $\bar{K}N$ interaction also generates quasi-bound states in kaon-nuclear systems, sometimes called kaonic nuclei. At the same time, the $\bar{K}N$ quasi-bound picture of the $Λ(1405)$ is also related to the discussion of hadronic molecules in hadron spectroscopy. Here an overview is presented of the theoretical studies developed for kaon-nucleon and kaon-nuclear systems. We start from the modern understanding of the $Λ(1405)$ resonance. We then discuss the $\bar{K}N$ interaction and various aspects of few-body kaonic nuclei. Heavier kaon-nuclear systems are examined from the viewpoint of nuclear many-body physics, with focus on the properties of antikaons in nuclear matter. Related topics, such as the $K^{-}p$ momentum correlation functions in high-energy collisions and the studies of kaonic atoms, are also discussed.
