Study of the $e^{+} e^{-} \to ϕ K^{+} K^{-}$ reaction within triangle dynamics and its implications for the $ϕ (2170)$

Xiang Wei, Cheng Chen, Si-Wei Liu +4

We revisit the $e^{+} e^{-} \to ϕ π^{+} π^{-}$ reaction within the $K_{1}$ - $K ˉ$ - $K$ triangle dynamics framework, in which the $e^{+} e^{-}$ pair annihilates through one-photon exchange approxim…

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…

Study of $χ_{c J} \to η η η^{'}$ via intermediate charmed meson loop mechanisms and its implications for non-observation of $η_{1} (1855)$ in $χ_{c J}$ decays

Xin-Ru Wang, Shu-Qi Wang, Shi-Dong Liu +3

Recently, the BESIII Collaboration reported the first observation of the decays $χ_{c J} \to η η η^{'}$ in order to search for the $1^{-+}$ exotic state $η_{1} (1855)$ . A partial wave…

Theoretical study on low-lying hidden-bottom and double-bottom tetraquark states

Lin-Juan Jiang, Chun-Sheng An, Cheng-Rong Deng +2

We perform a theoretical study on the spectrum of the low-lying hidden-bottom ( $q q ˉ b b ˉ$ with $q =$ $u$ , $d$ and $s$ ) and double-bottom ( $q q ˉ bb$ ) tetraquark states wit…

Analysis of $B_{s}^{0} \to X (3872) [ψ (2 S)] π^{+} π^{-} (K^{+} K^{-})$ decays

Hao-Nan Wang, Li-Sheng Geng, Gang Li +1

We have phenomenologically investigated the decays $B_{s}^{0} \to X (3872) π^{+} π^{-} (K^{+} K^{-})$ and $B_{s}^{0} \to ψ (2 S) π^{+} π^{-} (K^{+} K^{-})$ . In our analysis, the scalar meson $f_{0} (980)$ is form…
