Searching for signals of an exotic $I = 1, J^{P} = 2^{+}$ state of $D^{} K^{}$ nature and the structure of the $P_{c} (4312)$ in the $Λ_{b} \to Σ_{c}^{++} D^{-} K^{-}$ reaction

Jing Song, Zi-Ying Yang, Eulogio Oset

This paper investigates the decay process $Λ_{b} \to Σ_{c}^{++} D^{-} K^{-}$ with the objective of finding a predicted molecular state with isospin $I = 1$ , $J^{P} = 2^{+}$ of $D^{*} K^{*}$ nature, pl…

Photoproduction of the $Λ (1800)$

Melahat. Bayar, Jing Song, L. R. Dai +1

We have carried out a study of the $γ p \to p K^{+} K^{*-} (K^{*-} \to K^{-} π^{0})$ , $γ p \to p K^{+} K^{*-} (K^{*-} \to K ˉ^{0} π^{-})$ a…

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…
