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 4.24.2 GeV, and some narrow pentaquark resonances with hidden-bottom above 1111 GeV are found from corresponding scattering processes. Besides, the states NηcN\eta_{c}, NJ/ψNJ/\psi, NηbN\eta_{b} and NΥN\Upsilon with IJP=1212IJ^{P}=\frac{1}{2}\frac{1}{2}^{-}, as well as NJ/ψNJ/\psi and NΥN\Upsilon with IJP=1232IJ^{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.
