Rho Electroproduction and the Hadronic Contribution to Deeply Virtual Compton Scattering
A. Donnachie, J. Gravelis, G. Shaw
Abstract
A two-gluon-exchange model incorporating perturbative and non-perturbative effects is presented for rho electroproduction which provides an excellent description of all current data. This is then used to calculate the contribution from the rho to deeply virtual Compton scattering via the vector-meson-dominance transition rho -> gamma. This is found to be sufficiently large to provide a significant contribution through interference with the perturbative QCD term.
