The $Λ_{c}^{+} \to η π^{+} Λ$ reaction and the $Λ a_{0}^{+} (980)$ and $π^{+} Λ (1670)$ contributions

Man-Yu Duan, Wen-Tao Lyu, Chu-Wen Xiao +4

We study from the theoretical point of view the $Λ_{c}^{+} \to π^{+} η Λ$ reaction, recently measured by the Belle and BESIII Collaborations, where clear signals are observed for $a_0(980)…

Hidden Charm Decays of $Y (4626)$ in a $D_{s}^{*+} D_{s 1} (2536)^{-}$ Molecular Frame

Zi-Li Yue, Yue Pan, Dian-Yong Chen

In this work, we investigate the hidden charm decays properties of $Y (4626)$ , where $Y (4626)$ is assigned as a $S -$ wave $D_{s}^{*+} D_{s 1} (2536)^{-}$ molecular state with $J^{PC}=1^…

$X (4630)$ and $Y (4626)$ production in the $B^{+}$ and $B_{s}^{0}$ decays

Zhuo Yu, Qi Wu, Dian-Yong Chen

In the present work, we investigate the production of $X (4630)$ and $Y (4626)$ in $B^{+}$ and $B_{s}^{0}$ decays, where $X (4630)$ and $Y (4626)$ are considered as the $C -$ parity pigeon pa…

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…

Predicting hidden bottom molecular tetraquarks with a complex scaling method

Qing-Fu Song, Qi-Fang Lü, Dian-Yong Chen +1

In present work, we perform a coupled-channel analysis of $B_{(s)}^{(*)} B ˉ_{(s)}^{(*)}$ systems with the one-boson-exchange potentials. We first study the $I(J^{PC})=1(1^{+-})…
