The Infrared Behaviour of the Pure Yang-Mills Green Functions
Abstract
We review the infrared properties of the pure Yang-Mills correlators and discuss recent results concerning the two classes of low-momentum solutions for them reported in literature; i.e. decoupling and scaling solutions. We will mainly focuss on the Landau gauge and pay special attention to the results inferred from the analysis of the Dyson-Schwinger equations of the theory and from " quenched" lattice QCD. The results obtained from properly interplaying both approaches are strongly emphasized.
