Abstract.

The light-mass exotics with J PC = 1- + observed at BNL and CERN may have a simple explanation as dynamically generated resonances in \(\eta' \pi\) rescattering in the final-state interaction. This dynamics is mediated by the same anomalous glue which also generates the large mass of the \(\eta'\). OZI-violating processes are also potentially important to \(\eta'\) production in proton-proton collisions close to threshold.
