TY - JOUR A1 - Athenodorou, Andreas A1 - Boucaud, Philippe A1 - Soto, Feliciano de A1 - Rodríguez-Quintero, José A1 - Zafeiropoulos, Savvas T1 - Gluon Green functions free of quantum fluctuations T2 - Physics Letters B N2 - This letter reports on how the Wilson flow technique can efficaciously kill the short-distance quantum fluctuations of 2- and 3-gluon Green functions, remove the ΛQCD scale and destroy the transition from the confining non-perturbative to the asymptotically-free perturbative sector. After the Wilson flow, the behavior of the Green functions with momenta can be described in terms of the quasi-classical instanton background. The same behavior also occurs, before the Wilson flow, at low-momenta. This last result permits applications as, for instance, the detection of instanton phenomenological properties or a determination of the lattice spacing only from the gauge sector of the theory.
