Investigation of the $N\bar{D}$ system in quark delocalization color screening model

In this work we systematically calculate the pentaquark systems with quark contents $qqqq\bar{c}$ with the analyzed total spin and parity quantum numbers of $J^{P}=\frac{1}{2}^{-}$, $J^{P}=\frac{3}{2}^{-}$ and $J^{P}=\frac{5}{2}^{-}$, in the I=0, I=1 and I=2 isospin channels. The effective potentials between baryon and meson clusters are given, and the possible bound states are also investigated. Also, the study of the scattering process of the open channels is performed to look for possible resonance state. Our estimations indicate that several possible bound states and narrow baryon-meson resonances are found from corresponding the calculation processes.
