Study of hidden-charm, doubly-strange pentaquarks in $Λ_{b} \to J / ψ Ξ^{-} K^{+}$ and $Ξ_{b} \to J / ψ Ξ^{-} π^{+}$

L. Roca, J. Song, E. Oset

Hidden-charm pentaquark states with double strangeness, $P_{css}$ , have been predicted within the framework of unitary coupled-channel dynamics. In this work, we theoretically inve…

Molecular pentaquarks with hidden charm and double strangeness

L. Roca, J. Song, E. Oset

We analyze theoretically the coupled-channel meson-baryon interaction with global flavor $c ˉ css n$ and $c ˉ csss$ , where mesons are pseudoscalars or vectors and baryon…
