New spectrum of charm-strange meson with constituent quark model $c s ˉ$ contributions

Liu-Lin Wang, Xing-Meng Zhao, Xiao-Hai Liu +1

We systematically investigate the $S$ -wave interactions between Nambu-Goldstone bosons (NGBs) and charmed mesons in the $(S, I) = (1, 0)$ sector using the chiral unitary approach. The…

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…
