J/ψElectromagnetic Production at e^+e^- colliders

Abstract

Within the framework of QED we investigate the inclusive J/ψproduction at $e^{+}{e}^{-}$ colliders. It is expected to be as a further test to the charmonium production mechanisms and QED. We find that at the energies of CESR, BEPC, and TRISTAN (e.g. 4.0 GeV \leq \sqrt s \leq 60 GeV), the contributions of the concerned electromagnetic processes to the $J/\psi$ inclusive production are great, even dominant, thus they greatly affect the observation of the color-octet $J/\psi$ production signature at $e^{+}{e}^{-}$ colliders. The production of ψ', being similar to that of J/ψ's, is roughly estimated, and its influence on the observation of the color-octet J/ψproduction signature in e^+e^- collision is also discussed.
