摘要：

The reaction e+e- → ψ + X provides (i) a test of perturbative QCD, and (ii) a way to study even C states (such as ηc, χ, Higgs) recoiling against the ψ. Estimates of the cross section using QCD, a simple non-perturbative model, and a calculation of the contribution from two-body final states, suggest small but not unmeasurable cross sections. If mηc ≈ mψ, this may be a good way to find the ηc. © 1979.
