${\gamma }^{\ast }{\gamma }^{\ast }\to \rho \rho$ at very high energy

Abstract

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 $\rho$ mesons from virtual photons at very high energies should be measurable at the future linear collider (LC).
