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…

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)…

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…

How to unravel the nature of the $Σ^{*} (1430) (1/ 2^{-})$ state from correlation functions

Hai-Peng Li, Chu-Wen Xiao, Wei-Hong Liang +3

We calculate the correlation functions for the $K ˉ^{0} p, π^{+} Σ^{0}, π^{0} Σ^{+}, π^{+} Λ$ , and $η Σ^{+}$ states, which in the chiral unitary approach predict an excited $Σ^{*} (1/ 2^{-})$ state…

$a_{0} (1710)$ - $f_{0} (1710)$ mixing effect in the $D_{s}^{+} \to K_{S}^{0} K_{S}^{0} π^{+}$ decay

Yu-Wen Peng, Wei Liang, Xiaonu Xiong +1

With the measurements of the decay $D_{s}^{+} \to K_{S}^{0} K_{S}^{0} π^{+}$ by the BESIII Collaboration, we investigate this three-body weak decay via the chiral unitary approach for th…

Correlation function and the inverse problem in the $B D$ interaction

Hai-Peng Li, Jing-Yu Yi, Chu-Wen Xiao +3

We study the correlation functions of the $B^{0} D^{+}, B^{+} D^{0}$ system, which develops a bound state of approximately $40$ MeV, using inputs consistent with the $T_{cc} (3875)$ state.…
