    "abstract": "The electromagnetic interaction with quarks is investigated through a\nrelativistic, electromagnetic gauge-invariant treatment. Gluon dressing of the\nquark-photon vertex and the quark self-energy functions is described by the\ninhomogeneous Bethe-Salpeter equation in the ladder approximation and the\nSchwinger-Dyson equation in the rainbow approximation respectively. Results for\nthe calculation of the quark-photon vertex are presented in both the time-like\nand space-like regions of photon momentum squared, however emphasis is placed\non the space-like region relevant to electron scattering. The treatment\npresented here simultaneously addresses the role of dynamically generated\n$q\\bar{q}$ vector bound states and the approach to asymptotic behavior. The\nresulting description is therefore applicable over the entire range of momentum\ntransfers available in electron scattering experiments. Input parameters are\nlimited to the model gluon two-point function, which is chosen to reflect\nconfinement and asymptotic freedom, and are largely constrained by the obtained\nbound-state spectrum.",
