On the contribution of different coupling constants in the infrared regime of Yang-Mills theory: a Curci-Ferrari approach

Abstract

We investigate the influence of the different vertices of two-point correlation functions in the infrared regime of Yang-Mills theory using a phenomenological description. This regime is studied in Landau-gauge and using perturbation theory within a phenomenological massive model. We perform a one-loop calculation for two-point correlation functions taking into account the different role of the various interactions in the infrared. Our results show a good agreement with the lattice data.
