Jp. Ma et al., J PSI PRODUCTION AT PHOTON-PHOTON COLLIDERS AS A PROBE OF THE COLOR OCTET MECHANISM/, Physical review. D. Particles and fields, 57(1), 1998, pp. 606-609
We study J/psi production at photon-photon colliders, which can be rea
lized with Compton scattering of laser photons at e(+)e(-) colliders.
We find that the production rate through the color-octet channel is co
mparable to that through the color-singlet channel. Experimentally the
two mechanisms can be studied separately because the, processes have
different signals. [S0556-2821(98)04301-X].
