Looking for the hidden-charm pentaquark resonances in $J/\psi p$ 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 $J^P={\frac{1}{2}}^{-}$, ${\Sigma }_c{D}^{\ast }$ with $J^P={\frac{3}{2}}^{-}$, and ${\Sigma }_c{D}^{\ast }$ with $J^P={\frac{1}{2}}^{-}$, in the baryon-meson scattering process, respectively. Besides, the ${\Sigma }_c^{\ast }{D}^{\ast }$ 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.
