Pomeron exchange and exclusive electroproduction of rho-mesons in QCD

Abstract

A Pomeron-exchange model of exclusive electroproduction of $\rho$-mesons is examined using a dressed-quark propagator. It is shown that by representing the photon-$\rho$-meson-Pomeron coupling by a nonperturbative, confined-quark loop, one obtains predictions for $\rho$-meson electroproduction that are in good agreement with experiment.
