One or two poles for the $Ξ (1820)$ ?

R. Molina, Wei-Hong Liang, Chu-Wen Xiao +2

In this talk, we present a new interpretation for the recently observed $Ξ (1820)$ resonance. We recall that the chiral unitary approach for the interaction of pseudoscalar mesons w…

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}…

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…
