Investigating the hidden-charm and hidden-bottom pentaquark resonances in scattering process

Abstract

In the framework of quark delocalization color screening model, both the hidden-charm and hidden-bottom pentaquark resonances are studied in the hadron-hadron scattering process. A few narrow pentaquark resonances with hidden-charm above $4.2$ GeV, and some narrow pentaquark resonances with hidden-bottom above $11$ GeV are found from corresponding scattering processes. Besides, the states $N{\eta }_c$, $NJ/\psi$, $N{\eta }_b$ and $N{\rm Y}$ with $I{J}^P=\frac{1}{2}{\frac{1}{2}}^{-}$, as well as $NJ/\psi$ and $N{\rm Y}$ with $I{J}^P=\frac{1}{2}{\frac{3}{2}}^{-}$ are all possible to be bound by channel-coupling calculation. All these heavy pentaquarks are worth searching in the future experiments.
