Abstract

In this work double vector meson production in two-photon interactions at high energies is investigated considering saturation physics. We extend the color dipole picture for this process and study the energy and virtuality dependence of the forward differential cross section. A comparison with previous results is presented, and the contribution of the different photon polarizations is estimated.
