采用夸克对产生模型研究了几种类粲夸克素态的轻介子发射。将夸克对产生模型应用于四体系统，在紧致四夸克态假设下，计算了X（4700）$，Z_c（4430）$，Y（4230）$，Y（4360）$，Y（4390）$和Y（4660）$的π/K介子辐射。发现X（4700）和Z_c（4430）的π/K介子衰变宽度相对较小，而Y（4230），Y（4360），Y（4390）和Y（4660）的部分衰变宽度较大。我们期望我们对这些衰变行为的探索可以为未来的实验研究和理论解释提供有用的信息。本作品的内容可以在知识共享署名3.0许可协议的条款下使用。本作品的任何进一步分发都必须保留作者和作品标题、期刊引用和DOI的归属。文章由SCOAP 3资助，由中国物理学会、中国科学院高能物理研究所、中国科学院近代物理研究所和IOP出版有限公司授权出版。
We adopt the quark pair creation model to investigate the light meson emissions of several charmonium-like states. The quark pair creation model is applied to the four-body systems, and we calculate the pion/kaon emissions of the $X(4700)$, $Z_c(4430)$, $Y(4230)$, $Y(4360)$, $Y(4390)$ and $Y(4660)$ within the compact tetraquark assumptions. It is found that the pion/kaon decay widths for the $X(4700)$ and $Z_c(4430)$ are relatively small, while the partial decay widths for the resonances $Y(4230)$, $Y(4360)$, $Y(4390)$ and $Y(4660)$ are significant. We expect that our exploration of these decay behaviors can provide useful information for future experimental searches and theoretical interpretations.
