Abstract

A model for deeply virtual Compton scattering, based on analytical light-cone hadron wave functions, is presented and studied at energies currently accessible at Jefferson Laboratory, DESY, and beyond. It is shown that perpendicular vector components play an important role at Q²<10GeV² and that the meson-exchange diagrams are important at all energies. This could significantly impact the physical interpretation of the underlying hadronic amplitudes.
