Hard Exclusive QCD Processes at the Linear Collider

Abstract

The next generation of $e^+e^-$ colliders will offer a possibility of clean testing of QCD dynamics. Recent progress in the theoretical description of exclusive processes permits for many of them a consistent use of the perturbative QCD methods. We find that already on the basis of Born approximation, the exclusive diffractive production of two $\rho$ mesons from virtual photons at very high energies should be measurable at the linear collider (LC).Comment: 6 pages, talk given at the International Conference on Linear Colliders, Paris, 2004, 2 Postscript figures, uses sprocl.st
