On the absence of the Gribov copy problem in `effective locality' QCD calculations

About ten years ago the use of standard functional manipulations was demonstrated to imply an unexpected property satisfied by the fermionic Green’s functions of QCD and dubbed effective locality. This feature of QCD is non-perturbative as it results from a full gauge invariant summation of the gluonic degrees of freedom. This astounding result has lead to suspect that in a way or other, the famous Gribov copy problem had been somewhat overlooked. It is argued that it is not so.
