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…

Determination of the $K^{+} K ˉ^{0}$ scattering length and effective range and its relation to the $a_{0}^{+} (980)$ from the $χ_{c 1} \to π^{+} π^{-} η$ reaction

Hai-Peng Li, Jia-Xin Lin, Wei-Hong Liang +1

We analyze the clean cusp, seen in the $η π$ mass distribution with high precision of the $χ_{c 1} \to η π^{+} π^{-}$ reaction in the BESIII experiment, with the aim of making a precise d…

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…

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.…
