$P_{c} (4440)$ and $P_{c} (4457)$ decay into $D ˉ Σ_{c}$ and $D ˉ Λ_{c}$ and the spin of the $P_{c}$ states

Zi-Ying Yang, Jing Song, Wei-Hong Liang +1

We address the issue of the width and spin assignment of the $P_{c} (4440)$ and $P_{c} (4457)$ pentaquark states. We calculate the partial decays widths of the particles into $J / ψ N$ , $\b…

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…

Pentaquark molecular states with hidden bottom and double strangeness

Jing Song, Man-Yu Duan, Luis Roca +1

We investigate the meson-baryon interaction in coupled channels with the quantum numbers of the pentaquarks $P_{b ss}$ and $P_{b sss}$ . The interaction is derived from an extension o…
