(Field) symmetrization selection rules
Abstract
QCD and QED exhibit an infinite set of three-point Green's functions that contain only Okubo-Zweig-Iizuka (OZI) rule violating contributions, and (for QCD) are subleading in the large Nc expansion. The Green's functions describe the ``decay'' of a JPC=\{1,3,5,...\}-+ exotic hybrid meson current to two J=0 (hybrid) meson currents with identical P and C. We prove that the QCD amplitude for a neutral hybrid \{1,3,5,...\}-+ exotic current to create ηπ0 only comes from OZI rule violating contributions under certain conditions, and is subleading in Nc.
