Description
We study hidden-charm pentaquarks in the molecule picture of charmed baryon and anticharm meson in the approach of quark model and group theory. The strong decay of $P_c(4312)$, $P_c(4440)$, and $P_c(4457)$ are calculated for all 18 quark configurations and 47 states. It is found that all the possible states for Pc can decay through the $NJ/\psi$ channel and $N\eta_c$ channel for J=1/2, while only five states decay dominantly through the open-charm decay channels.
