The photon structure and exclusive production of vector mesons in gamma-gamma collisions
L. Motyka, B. Ziaja
Abstract
The process of exclusive vector meson production (gamma gamma to J/psi rho0) is studied for almost real photons. This process may be reduced to photoproduction of J/psi off the rho0 meson. We discuss the possibility of extracting the gluon distribution of rho0 and of the photon from such measurement. Predictions are also given for the reaction (e+e- to e+ e- J/psi rho0) for various e+e- cms energies typical for LEP and for the future linear colliders.
