Probing hidden-charm decay properties of $P_c$ states in a molecular scenario

Guang-Juan Wang, Li-Ye Xiao, Rui Chen +3

The $P_c(4312)$, $P_c(4440)$, and $P_c(4457)$ observed by the LHCb Collaboration are very likely to be $S$-wave ${\Sigma }_c{\bar{D}}^{(\ast )}$ molecular candidates due to their near-threshold…
