Description
Pion-exchange offers a natural explanation for Pc(4450)+ as a meson-baryon molecule, and implies a number of partner states. I discuss the properties of these partners and suggest experimental channels for their discovery. The molecular interpretation also implies that Pc(4450)+ is a mixture of isospins 1/2 and 3/2, which has characteristic signatures in production and decay. Several intriguing similarities suggest that Pc(4450)+ is an analogue of the X(3872) meson.
