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.
Fits using coupled channels and bare states show the psi(4660) as a conventional charmonium state above the Lambda_c pair threshold in both Belle and BESIII datasets.
The decay Υ(10753) → γ X_b0 is predicted to have partial width 0.2-1.5 keV and branching fraction 10^{-6} to 10^{-5} for binding energies 0-10 MeV, dominated by B1(') meson loops.
