Molecule pictures for the LHCb $P_c$ states
The first two pentaquark candidates $P_c(4380)$ and $P_c(4450)$ were observed by LHCb Collaboration in 2015. Recently, they presented their improved measurements in the Pc energy range, that a new narrow signal denoted as $P_c(4312)$ is reported and the previous observed structure $P_c(4450)$ is res...
