摘要：
The dominance of chi(0) in the data for e(+)e(-) -> psi + X-J(c (c) over bar) 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(*) D-J, where enhancements of D*D-0 and DD1 channels are predicted. Further tests and implications are discussed.
