QCD Propagators: What the lattice says

The quark and gluon propagators are the building blocks of QCD, but at low momentum they are significantly modified by nonperturbative physics, making them difficult to calculate. Over the years there have been many model calculations, sometimes with wildly conflicting results. Lattice gauge theory provides a way of calculating the propagators from first principles. I will give a summary of the progress made in this area, including some recent results with dynamical fermions, and give some examples of the extraction of some interesting quantities.
