本研究基于严格流-场对偶性构造六夸克流,经Fierz变换得到$X(2370)$衰变为赝标量介子的部分衰变宽度比,与BESIII实验数据吻合,支持其为三价胶子构成的胶球。
AI 中文摘要
本工作将具有$J^{PC}=0^{-+}$的$X(2370)$视为由三个价胶子构成的胶球,基于严格流-场对偶性构造六夸克流以得到胶球-夸克拉格朗日量;随后进行Fierz变换将夸克流玻色化为一系列三个赝标量介子;最终以模型无关方式得到该胶球衰变为三个赝标量介子的部分衰变宽度之比,该结果与BESIII合作组的实验数据相符,支持将$X(2370)$归类为胶球。
英文摘要
In this work, we take the $X(2370)$ with $J^{PC}=0^{-+}$ as a glueball consists of three valence gluons, and construct a six-quark current based on rigorous current-field duality to obtain the glueball-quark Lagrangian. Then we perform Fierz transformation to bosonize the quark current into a series of three pseudoscalar mesons. At last, we obtain ratios among the partial decay widths of the glueball to three pseudoscalar mesons in a model-independent way, which are compatible with the experimental data from the BESIII Collaboration and support assigning the $X(2370)$ as a glueball.
