Analysis of the strong decays of the $P_c(4312)$ as a pentaquark molecular state with QCD sum rules

Zhi-Gang Wang, Xu Wang

In this article, we tentatively assign the $P_c(4312)$ to be the $\bar{D}{\Sigma }_c$ pentaquark molecular state with the spin-parity $J^P={\frac{1}{2}}^{-}$, and discuss the factorizable an…
