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

Abstract

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.Comment: 13 pages, 9 figures; Proceedings of the workshop QCD-TNT-III, ECT* Trento, Sept. 2-6, 2013; references update
