Description
The unexpected discovery of dozens of exotic heavy hadrons since 2003 has provided a major challenge to our understanding of QCD. Among the zoo of exotic hadrons are 3 hidden-charm pentaquarks and 2 strange hidden-charm pentaquarks, only one of whose quantum numbers has been determined. We provide a simple explanation for the observed hidden-charm pentaquarks as bound states in Born-Oppenheimer potentials for QCD. Our prediction for their J^}PC}quantum numbers differs substantially from most previous predictions.
