Description
The Dyson-Schwinger/Bethe-Salpeter approach provides insight into many connected problems in QCD, proving to be especially powerful in describing processes that are dominated by chiral symmetry and its dynamical breaking. Being formulated in the continuum it avoids some of the difficulties encountered on the Lattice (e.g. chiral quarks etc) at the cost of having to introduce truncations.
I will discuss some of these truncations and how their extension leads to an improved understanding of the (spectrum of) hadrons, not only as concerns mesons and baryons but also exotic states such as tetraquarks.
Furthermore, I will report on recent progress in the generalization of these studies to finite temperature.
