(Field) symmetrization selection rules - art. no. 056009

QCD and QED exhibit an infinite set of three-point Green's functions that c ontain only Okubo-Zweig-Iizuka (OZI) rule violating contributions, and (for QCD) are subleading in the large N-c expansion. The Green's functions desc ribe the "decay" of a J(PC) = {1,3,5,...}(-+) exotic hybrid meson current t o two J = 0 (hybrid) meson currents with identical P and C. We prove that t he QCD amplitude for a neutral hybrid {1,3,5.... }(-) (+) exotic current to create eta pi (0) only comes from OZI rule violating contributions under c ertain conditions, and is subleading in N-c.
