Testing the molecular nature of the $Ω (2012)$ with the $ψ (3770) \to Ω ˉ K ˉ Ξ$ and $ψ (3770) \to Ω ˉ K ˉ Ξ^{*} (1530) (Ω ˉ K ˉ π Ξ)$ reactions

Jing Song, Wei-Hong Liang, Chu-Wen Xiao +2

We report on the reactions $ψ (3770) \to Ω ˉ^{+} K ˉ Ξ$ and $ψ (3770) \to Ω ˉ^{+} K ˉ Ξ^{*} (1530) (Ξ^{*} (1530) \to π Ξ$ ), and calculate the mass distributions $\frac{{\rm d}Γ}{{\rm d}…

Study of possible $D N D^{*}$ bound states

Victor Montesinos, Jing Song, Wei-Hong Liang +3

We start from a recently favored picture in which the $Λ_{c} (2940)$ and $Λ_{c} (2910)$ correspond mostly to $N D^{*}$ bound states with $J^{P} = 1/ 2^{-}, 3/ 2^{-}$ and then add a $D$ as a third…

Searching for the two poles of the $Ξ (1820)$ in the $ψ (3686) \to Ξ ˉ^{+} K ˉ^{0} Σ^{*-} (π^{-} Λ)$ decay

Man-Yu Duan, Jing Song, Wei-Hong Liang +1

We propose the reaction $ψ (3686) \to Ξ ˉ^{+} K ˉ^{0} Σ^{*-}$ , with the $Σ^{*-}$ decaying to $π^{-} Λ$ in order to show evidence for the existence of two $Ξ (1820)$ states, one aroun…

Contrasting observables related to the $N^{*} (1535)$ from the molecular or a genuine structure

Hai-Peng Li, Jing Song, Wei-Hong Liang +2

In this work we compare the predictions for the scattering length and effective range of the channels $K^{0} Σ^{+}, K^{+} Σ^{0}, K^{+} Λ$ and $η p$ , assuming the $N^{*} (1535)$ state as a molec…
