Looking for the hidden-charm pentaquark resonances in $J/ψp$ scattering
Abstract: In the framework of quark delocalization color screening model, the three new reported pentaquarks $P_{c}(4312)$, $P_{c}(4440)$, and $P_{c}(4457)$ can be identified as the hidden-charm molecular states $\Sigma_{c}D$ with $J{P}=\frac{1}{2}{-}$, $\Sigma_{c}D{*}$ with $J{P}=\frac{3}{2}{-}$, and $\Sigma_{c}D{*}$ with $J{P}=\frac{1}{2}{-}$, in the baryon-meson scattering process, respectively. Besides, the $\Sigma{}_{c}D{}$ of both $J{P}=\frac{1}{2}{-}$ and $J{P}=\frac{3}{2}{-}$ are also possible molecular pentaquarks. Moreover, the calculation is extended to the $P_{c}-$like molecular pentaquarks $P_{b}$. Several states with masses above $11$ GeV and narrow width are obtained. All these heavy pentaquarks are worth searching in the future experiments.
