摘要：

We calculate the production of narrow resonances with even charge conjugation 3PJ=1,2 in e+e- annihilation in the quarkonium and vectordominance models. We give unitarity bounds for Γ(3PJ → e+e-) in terms of Γ(3PJ → γγ) and Γ(3PJ → e+e-). The electromagnetic production dominates through the neutral current at low energies independent of details of the model. For masses above 10 GeV the situation is reversed. © 1979.
