Journal ArticleDOI
Gluon and ghost propagators in the Landau gauge: Deriving lattice results from Schwinger-Dyson equations
TL;DR: In this article, the authors show that the application of a novel gauge-invariant truncation scheme to the Schwinger-Dyson equations of QCD leads, in the Landau gauge, to an infrared finite gluon propagator and a divergent ghost propagator, in qualitative agreement with recent lattice data.
Journal ArticleDOI
Bridging a gap between continuum-QCD and ab initio predictions of hadron observables
TL;DR: In this article, it was shown that the renormalisation-group-invariant running-interaction predicted by contemporary analyses of QCD's gauge sector coincides with that required in order to describe Gro und-state hadron observables using a nonperturbative truncation of Dyson-Schwinger equations in the matter sector.
Journal ArticleDOI
Nonperturbative comparison of QCD effective charges
TL;DR: In this article, the authors studied the nonperturbative behavior of two versions of the QCD effective charge, one obtained from the pinch technique gluon self-energy, and one from the ghost-gluon vertex.
Journal ArticleDOI
Symmetry preserving truncations of the gap and Bethe-Salpeter equations
TL;DR: In this article, the quark-antiquark Bethe-Salpeter kernel was analyzed in terms of the gluon-quark scattering matrix, which was used to reveal the origin of two-particle-irreducible contributions, which are two-loop diagrams involving the three-gluon vertex.
Journal ArticleDOI
Natural constraints on the gluon-quark vertex
TL;DR: In this paper, a renormalization-group-invariant (RGI) running interaction was used to compute dressed-quark gap equation solutions with 1,660,000 distinct Ans\"atze vertex.
