Query: Quark correlations and gluon propagators in elastic vector meson
  production   We study the behavior of the differential cross section for vector meson
photoproduction at large momentum transfer in the two-gluon exchange model. We
focus on the treatment of two-quark correlation function in the proton and on
gluon propagators with a dynamically generated mass. We find that only the
large t region is sensitive to the particular details of these inputs.
