Abstract
We use a light-cone approach to solve the Schwinger-Dyson equation for the quark propagator. We show how this method can be used to solve the equation beyond the space-like region, to which one is usually restricted with the usual Euclidean-space approach. We work in the Landau gauge, and use an infrared-enhanced model for the gluon propagator and include instanton effects to get both confinement and vacuum condensates. With our models, reasonable fits to known quantities are obtained, resulting in a light-cone quark propagator that can be used for hadronic physics at all momentum transfers.
