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…

Nucleon pole contributions in $J / ψ \to N N ˉ π$ , $p p ˉ η$ , $p p ˉ η^{'}$ and $p p ˉ ω$ decays

Wei-Hong Liang, Peng-Nian Shen, Bing-Song Zou +1

Nucleon pole contributions in $J / ψ \to N N ˉ π$ , $p p ˉ η$ , $p p ˉ η^{'}$ and $p p ˉ ω$ decays are re-studied. Different contributions due to PS-PS and PS-PV coupl…
