【 摘 要 】

QCD and QED exhibit an infinite set of three-point Green's functions that contain only OZI rule violating contributions, and (for QCD) are subleading in the large N(sub c) expansion. We prove that the QCD amplitude for a neutral hybrid (l brace)1,3,5.(r brace)(+-) exotic current to create (eta)(pi)(sup 0) only comes from OZI rule violating contributions under certain conditions, and is subleading in N(sub c).
