论文摘要
Hexaquarks构成了像Tetra和Pentaquarks这样的复杂夸克系统的自然扩展。为此，在实验和理论中，$ d^*（2380）$的当前状态很快就会审查。在核子核子通道及其分析中，最近的高精度测量值已将$ d^*（2380）$建立为长期追求的Dibaryon通道中无可争议的共振。此$ i（j^p）= 0（3^+）$状态的重要特征是其狭窄的宽度，并且相对于$δ（1232）δ（1232）$阈值，其深层结合。它的衰减分支有利于理论计算，预测该状态的紧凑型六夸克性质。我们回顾了有关$ d^*（2380）$的实验和理论研究的当前状态以及将来可能带来的新物理方面。此外，我们回顾了$δ（1232）n $和$ n^*（1440）n $阈值的情况，在这里发现了许多可能分子性质的共鸣的证据，类似于Charmed和Beauty领域的情况。最后，我们简要讨论了调味夸克部门中狄巴里昂搜索的情况。
Hexaquarks constitute a natural extension of complex quark systems like also tetra- and pentaquarks do. To this end the current status of $d^*(2380)$ in both experiment and theory is shortly reviewed. Recent high-precision measurements in the nucleon-nucleon channel and analyses thereof have established $d^*(2380)$ as an indisputable resonance in the long-sought dibaryon channel. Important features of this $I(J^P) = 0(3^+)$ state are its narrow width and its deep binding relative to the $Δ(1232)Δ(1232)$ threshold. Its decay branchings favor theoretical calculations predicting a compact hexaquark nature of this state. We review the current status of experimental and theoretical studies on $d^*(2380)$ as well as new physics aspects it may bring in the future. In addition, we review the situation at the $Δ(1232) N$ and $N^*(1440)N$ thresholds, where evidence for a number of resonances of presumably molecular nature have been found -- similar to the situation in charmed and beauty sectors. Finally we briefly discuss the situation of dibaryon searches in the flavored quark sectors.
