论文摘要
LHCB的2020年宣布狭窄的结构$ x(6900)$ in Di-$ j/ψ$ spectrum-潜在的$ c \ bar c c \ bar c $ state-已在Hadro-spectroscopery开设了一个新时代。在本次演讲中,我们简要调查理论在此事件之前进行了研究,检查观察到的频谱的关键特征,然后讨论后续理论研究(包括作者自己的动态diquark模型)如何解释了这些特征。我们最终以能够区分竞争解释的实验的建议。
The 2020 announcement by LHCb of a narrow structure $X(6900)$ in the di-$J/ψ$ spectrum -- a potential $c\bar c c\bar c$ state -- has opened a new era in hadronic spectroscopy. In this talk, we briefly survey theory works preceding this event, examine key features of the observed spectrum, and then discuss how subsequent theory studies (including with the author's own dynamical diquark model) have interpreted these features. We conclude with proposals for experiments capable of distinguishing competing interpretations.
