Confirming the existence of a new higher charmonium $ψ (4500)$ by the newly released data of $e^{+} e^{-} \to K^{+} K^{-} J / ψ$

Jun-Zhang Wang, Xiang Liu

Recently, the BESIII Collaboration published the Born cross section of $e^{+} e^{-} \to K^{+} K^{-} J / ψ$ , in which a new vector enhancement structure $Y (4500)$ was observed for the first tim…

The $X (3872) \to J / ψ π γ$ and $X (3872) \to J / ψ π π γ$ decays

Qi Wu, Jun-Zhang Wang, Shi-Lin Zhu

We study the $ρ$ and $ω$ meson contribution to the radiative decays $X (3872) \to J / ψ π γ$ and $X (3872) \to J / ψ π π γ$ . The $X (3872) \to J / ψ π γ$ is dominated by the $…

Connection between near the $D_{s}^{+} D_{s}^{-}$ threshold enhancement in $B^{+} \to D_{s}^{+} D_{s}^{-} K^{+}$ and conventional charmonium $χ_{c 0} (2 P)$

Dan Guo, Jun-Zhang Wang, Dian-Yong Chen +1

Focusing on recent measurement of $B^{+} \to D_{s}^{+} D_{s}^{-} K^{+}$ process given by the LHCb Collaboration, we propose that this newly observed near the $D_{s}^{+} D_{s}^{-}$ threshold enhancement c…

The role of the $ω (4 S)$ and $ω (3 D)$ states in mediating the $e^{+} e^{-} \to ω η$ and $ω π^{0} π^{0}$ processes

Qin-Song Zhou, Jun-Zhang Wang, Xiang Liu

The $e^{+} e^{-} \to ω η$ and $e^{+} e^{-} \to ω π^{0} π^{0}$ processes are ideal platforms to search for higher $ω$ states. Focusing on the observations of two enhancement structures around 2.2 GeV e…

Improved understanding of the peaking phenomenon existing in the new di- $J / ψ$ invariant mass spectrum from the CMS Collaboration

Jun-Zhang Wang, Xiang Liu

Very recently, the CMS Collaboration reported a peaking phenomenon existing in the di- $J / ψ$ invariant mass spectrum from $pp$ collision, by which the $X (6900)$ structure announced…

Identifying the contribution of higher $ρ$ mesons around 2 GeV in the $e^{+} e^{-} \to ω π^{0}$ and $e^{+} e^{-} \to ρ η^{'}$ processes

Qin-Song Zhou, Jun-Zhang Wang, Xiang Liu +1

The properties of the light vector meson states around 2.0 GeV have been poorly understood for a long time, which has become a barrier to the expansion to higher light vector meson…
