Abstract
In this talk, we will present a coupled-channel analysis of the $J/\psi p$ spectrumn, in which the $P_c$ states are treated as $\Sigma_c^{()}\bar{D}^{()}$ molecules. The effective potentials involve both the contact potentials and OPE and their renormalization group behaviour is investigated. The approach yields a very good description of the data. A narrow state around 4.38 GeV associated with the $\Sigma_c^*\bar{D}$ molecule is predicted from HQSS, and has a clear manifestation in the data.
