Description
The dominance of χ0 in the data for e+e-→ψ+χJ(cc) is shown to violate Okubo-Zweig-Iizuka rule factorization. Single gluon exchange gives a nonfactorizing effective S·L interaction that generates a large scalar production amplitude. This also has observable effects near threshold in e+e-→D(*)DJ, where enhancements of D*D0 and DD1 channels are predicted. Further tests and implications are discussed.
