We show that the correlation functions of ghosts and gluons for the pure Yang-Mills theory in Landau gauge can be accurately reproduced for all momenta by a one-loop calculation. The key point is to use a massive extension of the Faddeev-Popov action. The agreement with lattice simulation is excellent in d=4. The one-loop calculation also reproduces all the characteristic features of the lattice simulations in d=3 and naturally explains the peculiarities of the propagators in d=2.

Nonperturbative properties of Yang–Mills theories (2018, methodology): “Further previous studies of the correlation functions of three-dimensional Yang-Mills theory were done with functional methods in [91, 171, 189, 348, 485, 512, 519–521], with the (refined) GZ framework in [522] and with a massive extension of Yang-Mills theory in [300, 301, 305, 315].”
The QCD running coupling (2016, methodology): “o a three-gluon interaction. 4.15 Curci-Fermi model Tissier and collaborators have computed the gluon and ghost propagators, and the quark-gluon vertex with a 1-loop model including a gluon mass term [386]. They used the Curci-Ferrari model [387] as an eective description. The resulting coupling is ”
