Production of hidden-charm molecular candidates in $ψ (4660)$ decays

Xiao-Yun Wang, Ya-Rong Wang, Shi-Dong Liu +2

We investigate the production of several hidden-charm exotic candidates, including $Z_{c} (3900)$ , $Z_{c} (4020)$ , $Z_{cs} (3985)$ , and $Z_{2} (4250)$ , in $ψ (4660)$ decays under the assumpti…

Probing the nature of $D_{1} K$ and $D_{2} K$ molecules through $D_{s}^{(*)} π π$ and $D_{s 0 (s 1)} π$ decays

Xing-Meng Zhao, Liu-Lin Wang, Ying-Bo He +2

We study the two- and three-body decays of the $I = 0$ $D_{1} K$ and $D_{2} K$ molecular states $T_{c s ˉ 1}^{*}$ and $T_{c s ˉ 2}^{*}$ into $D_{s}^{(*)}$ mesons and pions. Triangle singular…

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…

Pionic transitions of the spin-2 partner of $X (3872)$ to $χ_{c J}$

Shi-Dong Liu, Fan Wang, Zhao-Sai Jia +3

We investigated the pionic transitions between the $X_{2}$ [spin-2 partner of the $X (3872)$ ] and $χ_{c 1, 2}$ using a nonrelativistic effective field theory. The $X_{2}$ is assumed to be…

More hidden heavy quarkonium molecules and their discovery decay modes

Gang Li, Xiao Hai Liu, Zhu Zhou

To validate the molecular description of the observed $Z_{b} (10610) / Z_{b} (10650)$ and $Z_{c} (3900) / Z_{c} (4025)$ , it is valuable to investigate their counterparts, denoted as $Z_{QV}^{(\pri…
