Strong decay mode $J/\psi p$ of hidden charm pentaquark states $P_c^{+}(4380)$ and $P_c^{+}(4450)$ in ${\Sigma }_c{\bar{D}}^{\ast }$ molecular scenario

Qi-Fang Lü, Yu-Bing Dong

We study the strong decay channels $P_c^{+}(4380)\to J/\psi p$ and $P_c^{+}(4450)\to J/\psi p$ under ${\Sigma }_c{\bar{D}}^{\ast }$ molecular state ansatz. With various spin-parity assignments, the partial…
