Manifestations of anomalous glue: light-mass exotic mesons and the eta-prime nucleon coupling constant
Abstract
The light-mass exotics with JPC=1-+ observed at BNL and CERN may have a simple explanation as dynamically generated resonances in eta-prime 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-prime. OZI violating processes are also potentially important to eta-prime production in proton-proton collisions close to threshold.
