Gauge-invariant truncation scheme for the Schwinger-Dyson equations of QCD
arXiv:0712.2707 · doi:10.1103/PhysRevD.77.061702
Abstract
We present a new truncation scheme for the Schwinger-Dyson equations of QCD that respects gauge invariance at any level of the dressed loop expansion. When applied to the gluon self-energy, it allows for its non-perturbative treatment without compromising the transversality of the solution, even when entire sets of diagrams (most notably the ghost loops) are omitted, or treated perturbatively.
