Description
The combination of Dyson-Schwinger and Bethe-Salpeter equations allows, in principle, for an *ab-initio* continuum-QCD study of hadrons and their properties. Glueballs, mesons, baryons, etc. are all treated in a unified framework. Moreover it has the advantage that that it gives access to all momentum regimes and all quark masses, connecting the deep infrared to perturbative QCD and light- and heavy-quark physics.
The major downside is, however, the necessity of truncationg both Dyson-Schwinger and Bethe-Salpeter equations to make the problem tractable. However, guided by symmetries such as Poincare invariance, chiral symmetry, etc. one can define a systematic procedure to successively incorporate interaction terms in the calculations. The purpose of the presentation is to discuss this procedure as well as to illustrate it with some selected results.
