Abstract: 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.<br />Comment: 9 pages, 2 figures; v3: typos corrected; v2: discussion on numerical results expanded, considerations about the Kugo-Ojima confinement criterion added
