J/ψ+η′ Production ine+e−-annihilation: A perturbative QCD calculation

The cross section for the reactione+e−→3S1+1S0 is calculated in the framework of perturbative QCD, using the nonrelativistic approximation for the3S1 and1S0 bound states. The model is applied toJ/Ψ plus η,η,η′, andl production. We find extremely small rates in contrast to previous estimates based on vector meson dominance and discuss possible reasons for this difference.
