Query: Nambu-Jona-Lasinio model correlation functions from QCD   We treat quantum chromodynamics (QCD) using a set of Dyson-Schwinger
equations derived, in differential form, with the Bender-Milton-Savage
technique. In this way, we are able to derive the low energy limit that assumes
the form of a non-local Nambu-Jona-Lasinio model with all the parameters
properly fixed by the QCD Lagrangian and the determination of the mass gap of
the gluon sector.
