Introduces a hybrid loop function in Bethe-Salpeter unitarization within the local hidden gauge approach to generate hidden-charm pentaquarks, reproducing six known states and predicting new ones in the S=-1, I=1 sector.
Coupled-channel calculations show Pc and Pcs states as molecular bound states with RMS radii 0.5-2 fm when heavy-quark spin symmetry is respected across all channels.
