  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.
