Decay behaviors of the $P_c$ hadronic molecules

Abstract

In this proceeding, we present our recent work on decay behaviors of the $P_c$ hadronic molecules, which can help to disentangle the nature of the two $P_c$ pentaquark-like structures. The results turn out that the relative ratio of the decays of $P_c^{+}(4380)$ to ${\bar{D}}^{\ast }{\Lambda }_c$ and $J/\psi p$ is very different for $P_c$ being a ${\bar{D}}^{\ast }{\Sigma }_c$ or $\bar{D}{\Sigma }_c^{\ast }$ bound state with $J^P={\frac{3}{2}}^{-}$. And from the total decay width, we find that $P_c(4380)$ being a $\bar{D}{\Sigma }_c^{\ast }$ molecule state with $J^P={\frac{3}{2}}^{-}$ and $P_c(4450)$ being a ${\bar{D}}^{\ast }{\Sigma }_c$ molecule state with $J^P={\frac{5}{2}}^{+}$ is more favorable to the experimental data.
