$J/Psi$-Production at Photon-Photon Colliders as a Probe of the Color Octet Mechanism


Abstract in English

We study $J/Psi$ production at photon-photon colliders, which can be realised with Compton scaterring of laser photons at $e^+e^-$ colliders. We find that the production rate through the color-octet channel is comparable to that through the color-singlet channel. Experimentally the two mechanisms can be studied separately because the processes have different signals.
