$J / ψ Λ$ femtoscopy and the nature of $P_{ψ s}^{Λ} (4338)$

Yi-Bo Shen, Zhi-Wei Liu, Ming-Zhu Liu +4

Over the past two decades, numerous exotic hadron states have been discovered, yet their underlying nature remains unclear. It is widely acknowledged that understanding hadron-hadr…

Revisiting the $Λ_{c}^{+} \to Λ η π^{+}$ and the roles of intermediate resonances

En Wang, Wen-Tao Lyu, Man-Yu Duan +4

In this paper, we first review the theoretical and experimental studies of the process $Λ_{c}^{+} \to π^{+} η Λ$ . Motivated by the recent BESIII and Belle measurements, we have conducted…

Role of $a_{0} (980)$ in the decays $D^{0} \to K^{+} K^{-} η$ and $π^{+} π^{-} η$

Sara Rahmani, Wei Liang, Yu-Wen Peng +3

In present work, we study the reactions $D^{0} \to K^{+} K^{-} η$ and $D^{0} \to π^{+} π^{-} η$ , and find that the $a_{0} (980)$ state plays a dominant role. At the quar…

Determination of the binding and $D K$ probability of the $D_{s 0}^{*} (2317)$ from the $(D ˉ K ˉ)^{-}$ mass distributions in $Λ_{b} \to Λ_{c} (D ˉ K ˉ)^{-}$ decays

Hai-Peng Li, Wei-Hong Liang, Chu-Wen Xiao +2

We study the $Λ_{b} \to Λ_{c} D ˉ^{0} K^{-}$ and $Λ_{b} \to Λ_{c} D^{-} K ˉ^{0}$ decays which proceed via a Cabibbo and $N_{c}$ favored process of external emission, and we determin…

Possible signal of an exotic $I = 1$ , $J = 2$ state in the $B \to D^{*-} D^{+} K^{+}$ reaction

Wen-Tao Lyu, Man-Yu Duan, Chu-Wen Xiao +2

We study the \proc reaction, showing that a peak in the \dk mass distribution around 2834 MeV reported by LHCb could be associated with a theoretical exotic state with that mass, a…
