Constraints on the IR behaviour of gluon and ghost propagator from Ward-Slavnov-Taylor identities

Abstract

We consider the constraints of the Slavnov-Taylor identity of the IR behaviour of gluon and ghost propagators and their compatibility with solutions of the ghost Dyson-Schwinger equation and with the lattice picture.
