$K (1690)$ signal from COMPASS as a strange hybrid state

Bing Chen, Ri-Qing Qian, Xiang Liu

A pseudoscalar resonance structure, denoted as the $K (1690)$ , was recently discovered by the COMPASS Collaboration in the scattering reaction $K^{-} + p \to K^{-} π^{-} π^{+} + p$ . If the $K(1690…

Revisiting charmonium hybrid spectroscopy

Ri-Qing Qian, Bing Chen, Xiang Liu

Hadrons with explicit gluonic degrees of freedom, such as charmonium hybrids, are key to understanding nonperturbative behavior of strong interaction, yet they remain experimentall…

Unified coupled-channel description for the five near-threshold structures $ψ (3770)$ , $G (3900)$ , $R (3760)$ , $R (3780)$ and $R (3810)$ from $e^{+} e^{-}$ annihilation

Ri-Qing Qian, Xiang Liu

The recent observation of multiple near-threshold structures in $e^{+} e^{-}$ annihilation-including $ψ (3770)$ , $G (3900)$ , $R (3760)$ , $R (3780)$ , and $R (3810)$ -reveals limitations in exi…

Discovery potential of charmonium $2 P$ states through the $e^{+} e^{-} \to γ D D ˉ$ processes

Tian-Le Gao, Ri-Qing Qian, Xiang Liu

In this work, we investigate the production of charmonium $2 P$ states via the $e^{+} e^{-} \to γ D D ˉ$ process at $s = 4.23$ GeV. Using the measured cross-section data for $e^+…

Production of charmonium $χ_{c J} (2 P)$ plus one $ω$ meson by $e^{+} e^{-}$ annihilation

Ri-Qing Qian, Xiang Liu

Inspired by the recent observation of $e^{+} e^{-} \to ω X (3872)$ by the BESIII Collaboration, in this work we study the production of the charmonium $χ_{c J} (2 P)$ by $e^{+} e^{-}$ annihilation…

Toy model to understand oscillatory behavior in timelike nucleon form factors

Ri-Qing Qian, Zhan-Wei Liu, Xu Cao +1

To understand the oscillatory behavior exhibited in the timelike electromagnetic form factors of nucleons, we propose a toy model based on the Jost function of the $N N ˉ$ pair i…

Predicted $Λ Λ ˉ$ and $Ξ^{-} Ξ ˉ^{+}$ decay modes of the charmoniumlike $Y (4230)$

Ri-Qing Qian, Qi Huang, Xiang Liu

In this work, we predict the light hadronic decay channels $Y (4230) \to Λ Λ ˉ$ and $Ξ^{-} Ξ ˉ^{+}$ when treating the $Y (4230)$ as a vector charmonium state. By the hadronic loop mechan…

Charmonium decays into $Λ_{c} Λ ˉ_{c}$ pair governed by the hadronic loop mechanism

Ri-Qing Qian, Jun-Zhang Wang, Xiang Liu +1

In this work, we investigate the open-charm decay process $ψ \to Λ_{c} Λ ˉ_{c}$ via the hadronic loop mechanism for vector charmonia above $Λ_{c} Λ ˉ_{c}$ threshold. The branching ratios o…

Are the $Y$ states around 4.6 GeV from $e^{+} e^{-}$ annihilation higher charmonia?

Jun-Zhang Wang, Ri-Qing Qian, Xiang Liu +1

In this work, we present the mass spectrum of higher charomona around and above 4.6 GeV by adopting the unquenched potential model. We perform a combined fit to the updated experim…
