标题： Revisit the $Z_c(4025)$ structure observed by BESIII in the $e^+e^- \to (D^*\bar{D}^*)^{\pm,0}π^{\mp,0}$ reactions at $\sqrt{s}=4.26$ GeV

摘要： 在局部隐含规范形式框架下，我们重新分析了隐含魅夸克的矢量-矢量介子$D^*\bar{D}^*$、$K^*\bar{K}^*$和$\rho\rho$与量子数$I(J^P)=1(1^+)$的相互作用。估计表明，$D^*\bar{D}^*$系统可能在约 4010 MeV 处形成束缚态。 通过将我们的理论估计与BESIII在$\sqrt{s}=4.26$ GeV 下对$e^+e^- \to (D^*\bar{D}^*)^{\pm}\pi^{\mp}$和$e^+e^- \to (D^*\bar{D}^*) ^{0}\pi^{0}$反应的测量结果进行比较，我们发现BESIII在$D^*\bar{D}^*$不变质量分布中观察到的$Z_c(4025)$的增强结构可能由一个浅层$D^*\bar{D}^*$结合态来解释。 显示英文摘要

摘要： Within the framework of the local hidden gauge formalism, we have reanalyzed the hidden-charm vector-vector meson $D^*\bar{D}^*$, $K^*\bar{K}^*$, and $\rho\rho$ interactions with the quantum numbers $I(J^P)=1(1^+)$. The estimation indicates that $D^*\bar{D}^*$ system could form a bound state around 4010 MeV. By comparing our theoretical estimation with the BESIII measurements of the $e^+e^- \to (D^*\bar{D}^*)^{\pm}\pi^{\mp}$ and $e^+e^- \to (D^*\bar{D}^*) ^{0}\pi^{0}$ reactions at $\sqrt{s}=4.26$ GeV , we find that the enhancement structure of the $Z_c(4025)$ in the $D^*\bar{D}^*$ invariant mass distribution observed by BESIII could be interpreted by a shallow $D^*\bar{D}^*$ bound state.
