Gluon and ghost propagators in the Landau gauge: Deriving lattice   results from Schwinger-Dyson equations
  We show that the application of a novel gauge invariant truncation scheme to the Schwinger-Dyson equations of QCD leads, in the Landau gauge, to an infrared finite gluon propagator and a divergent ghost propagator, in qualitative agreement with recent lattice data.
