论文摘要
多功能系统的动态与核物理的多个领域相关。但是，即使是最简单的系统，两个和三个龙头也很难在实验上进行准备和研究。在这里，我们展示了如何使用第一原则晶格QCD结果提取此信息。我们（1）将相对论的三体量化条件扩展到陌生部门，这首先预测了最大同胞素的三个KAON系统的激发水平有限体积频谱，（2）呈现第一个晶格QCD计算该系统中该系统激发级别的电平计算。我们将我们的预测与此处报告的晶格结果以及以前的基础状态计算进行了比较，并找到了很好的一致性。
The dynamics of multi-kaon systems are of relevance for several areas of nuclear physics. However, even the simplest systems, two and three kaons, are hard to prepare and study experimentally. Here we show how to extract this information using first-principle lattice QCD results. We (1) extend the relativistic three-body quantization condition to the strangeness sector, predicting for the first time the excited level finite-volume spectrum of three kaon systems at maximal isospin, and (2) present a first lattice QCD calculation of the excited levels of this system in a finite box. We compare our predictions with the lattice results reported here and with previous ground state calculations and find very good agreement.
