Description
In this paper, the two-photon interactions at high energies are investigated considering different approaches for the QCD dynamics. In particular, we calculate the γ*γ* total cross section in different theoretical approaches and present a comparison among the predictions of the BFKL dynamics at leading and next-to-leading order with those from saturation physics. We analyse the possibility that the future linear colliders could discriminate between these different approaches
