    "abstract": "A Dyson-Schwinger-based model of pomeron exchange is employed to calculate\ndiffractive rho-, phi- and J/psi-meson electroproduction cross sections. It is\nshown that the magnitude of the current-quark mass m_f of the quark and\nantiquark inside the produced vector meson determines the onset of the\nasymptotic-q^2 power-law behavior of the cross section, and how correlated\nquark-exchanges are included to provide a complete picture of the diffractive\nelectroproduction of light vector mesons applicable over all energies and\nphoton momenta q^2.",
