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

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

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.
