$γ^* γ^* \to ρρ$ at very high energy

The next generation of $e^+e^-$-colliders will offer a possibility of clean testing of QCD dynamics in the Regge limit. Recent progress in the theoretical description of exclusive processes permits for many of them a consistent use of the perturbative QCD methods. We advocate that the exclusive diffractive production of two $ρ$ mesons from virtual photons at very high energies should be measurable at the future linear collider (LC).
