J/\psi Electromagnetic Production at e^+e^- colliders
Abstract
Within the framework of QED we investigate the inclusive J/\psi production at 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 inclusive production are great, even dominant, thus they greatly affect the observation of the color-octet production signature at colliders. The production of \psi', being similar to that of J/\psi's, is roughly estimated, and its influence on the observation of the color-octet J/\psi production signature in e^+e^- collision is also discussed.
