dc.description.abstractPerturbative QCD predicts that the growth of the gluon density at high energies should saturate, forming a Color Glass Condensate (CGC), which is described in mean field approximation by the Balitsky-Kovchegov (BK) equation. in this paper we study the gamma gamma interactions at high energies and estimate the main observables which will be probed at future linear colliders using the color dipole picture. We discuss in detail the dipole-dipole cross section and propose a new relation between this quantity and the dipole scattering amplitude. the total gamma gamma, gamma*gamma* cross sections and the real photon structure function F(2)(gamma) (x, Q(2)) are calculated using the recent solution of the BK equation with running coupling constant and the predictions are compared with those obtained using phenomenological models for the dipoledipole cross section and scattering amplitude. We demonstrate that these models are able to describe the LEP data at high energies, but predict a very different behavior for the observables at higher energies. Therefore we conclude that the study of gamma gamma interactions can be useful to constrain the QCD dynamics.en
