A heuristic derivation of an effective QCD coupling dominated by gluon condensates

We have recently proposed that an effective strong running coupling, which may reproduce the hadronic phenomenology through the Schwinger-Dyson approach in the rainbow-ladder approximation, can originate from the interplay of the dimension 2 gluon condensate (A^2) and the dimension 4 gluon condensate (F^2). Here we give an alternative, heuristic derivation of this effective running coupling.
