Description
Using a scan sample taken at center-of-mass energies from 3.773 GeV to 4.95 GeV with an integrated luminosity of 22/fb, the properties of XYZ states are investigated at BESIII. The cross sections of $e^+e^- \rightarrow D^{*+} D^{*-}$ and $D^{*+} D^-$, $e^+e^- \rightarrow K^+ K^- J/\psi$, and $\pi^+ \pi^- \psi_2(3823)$ are measured. New decay modes of $X(3872) \rightarrow \pi^0 \chi_{c0}$ and $\pi \pi \chi_{c0}$ are searched where the $X(3872)$ is produced via the process of $e^+e^- \rightarrow \gamma X(3872)$.
