Abstract

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