Isospin breaking decays as a diagnosis of the hadronic molecular structure of the Pc(4457)

The LHCb Collaboration announced the observation of three narrow structures consistent with hidden-charm pentaquark states. They are candidates of hadronic molecules formed of a pair of a charmed baryon and an anticharmed meson. Among them, the Pc(4457) mass is consistent with earlier predictions of...
