Abstract
Exploiting the gauge-invariant properties of the PT-BFM truncation scheme for the gluon Schwinger-Dyson equation, we estimate the individual non-perturbative contribution of the "one-loop dressed" ghost loop to the gluon propagator. Using the available quenched lattice data for the gluon and the ghost propagators in d=4 and d=3, we determine how the overall shape of the gluon propagator is affected by the removal of the ghost loop, and what are the consequences on the phenomenon of gluon mass generation.
