Abstract
It is essential to know the space-time structure of the nonlocal vacuum
condensates for application to medium energy processes. Using the
Dyson-Schwinger formalism in the rainbow approximation for the quark
propagator, we study the nonlocal quark condensate and model forms for the
nonperturbative gluon propagator constrained by fits to local condensates and
deep inelastic scattering with nucleon targets.
