Dipion transitions from $X (3872)$ to $χ_{c J} (J = 0, 1, 2)$

Qi Wu, Zhong-Quan Sun, Dian-Yong Chen +2

In this work, we investigate the dipion transition processes $X (3872) \to π π χ_{c J} (J = 0, 1, 2)$ within the framework of heavy hadron chiral perturbation theory, treating $X (3872)$ as…

Light hadronic decays of spin-0 partner of $X (3872)$

Hong-Shuo Gao, Zu-Xin Cai, Gang Li +1

The $X (3872)$ is theoretically predicted to have a spin-0 partner state denoted as $X_{0}$ . Assuming the $X_{0}$ as a $D D ˉ$ molecular bound state, we calculate the decay widths of…

Hadronic decays of possible pseudoscalar $P$ -wave $D D ˉ^{} / D ˉ D^{}$ molecular state

Shi-Dong Liu, Qi Wu, Gang Li

Recently, the new structure $G (3900)$ observed by the BESIII Collaboration in the $e^{+} e^{-} \to D D ˉ$ was identified to be the $P$ -wave $D D ˉ^{*} / D ˉ D^{*}$ vector molecu…

Dipionic transitions of $Y (4500)$ to $J / ψ$

Shidong Liu, Qi Wu, Gang Li

We, using an effective Lagrangian approach, investigated the dipionic transition of the $Y (4500)$ newly well established in the process $e^{+} e^{-} \to K^{+} K^{-} J / ψ$ . In this study, the $…

Hidden charmed decays of $X (3872)$ within the $D D ˉ^{*}$ molecular framework

Hao-Dong Cai, Zhao-Sai Jia, Gang Li +1

The dipionic transition of the $X (3872)$ to the $η_{c}$ was investigated using an effective Lagrangian approach. In this study, the $X (3872)$ was assumed to be a $D\bar{D}^\ast + \te…

Investigation of box diagrams for the peak of $Z_{cs} (3985)$ in $e^{+} e^{-} \to D_{s}^{-} D^{* 0} K^{+}$ and $D_{s}^{*-} D^{0} K^{+}$

Yuan-Xin Zheng, Gang Li, Shi-Dong Liu +1

The BESIII collaboration recently observed a charged hidden-charm structure with strangeness in the recoil mass spectrum of $K^{+}$ in the processes $e^{+} e^{-} \to D_{s}^{-} D^{* 0} K^{+}$ or…
