An exploration of the Schwinger-Dyson equations of QCD


It is widely believed that the physics of mesons and baryons may be adequately described by QCD. However, unlike the perturbative region, a clear understanding of the strongly-coupled part of QCD has been problematic since inception. One of the theoretical tools that we can use to understand the non-perturbative physics of the QCD Lagrangian are the Schwinger-Dyson equations. I will introduce the Schwinger-Dyson equations of QCD and explain how solutions can be obtained. I will also discuss the two types of solutions that appear to exist in quenched QCD and how these may be related to the confinement of colored particles.
