Threshold effects as the origin of $Y (4500)$ observed in $e^{+} e^{-} \to J / ψ K^{+} K^{-}$

Xiao-Yun Wang, Liu-Lin Wang, Xiao-Hai Liu +1

The BESIII collaboration has recently observed a resonant structure $Y (4500)$ in $e^{+} e^{-} \to J / ψ K^{+} K^{-}$ , whose origin remains unresolved. In this study, we analyze the cross…

Production and decay of anticharmed pentaquark state with quark content $c ˉ s u dd$

Shi-Dong Liu, Xiao-Yun Wang, Xiao-Hai Liu +1

We used an effective Lagrangian approach to investigate the production of the anticharmed pentaquark state $P_{c ˉ s}^{(*) -}$ with the minimal quark content $c ˉ s u dd$ in the…

Theoretical study of the open-flavor tetraquark $T_{c s ˉ} (2900)$ in the process $B ˉ_{s}^{0} \to K^{0} D^{0} π^{0}$

Wen-Tao Lyu, Man-Yu Duan, Xiaoyu Wang +2

Recently, the LHCb Collaboration has measured two decay processes $B^{0} \to D ˉ^{0} D_{s}^{+} π^{-}$ and $B^{+} \to D^{-} D_{s}^{+} π^{+}$ related to isospin symmetry, where two new open-flavor tetraqua…
