On propagators and three-point functions in Landau gauge QCD and QCD-like theories

Understand

Recent progress in our studies of propagators and three-point functions in Landau gauge for QCD and QCD-like theories is presented.

• Special emphasis is put on the properties of the three-gluon vertex and the quark-gluon vertex.
• The effect of unquenching is investigated.
• Furthermore, an exploratory study for a large number of light flavours is described, from where clear evidence for the qualitative behaviour of propagators in the so-called conformal window can be extracted.
