RT Journal Article T1 An instanton picture O.P.E. condensate? A1 de Soto, Feliciano A1 Boucaud, P. A1 Donini, A. A1 Leroy, J. P. A1 Le Yaouanc, A. A1 Micheli, J. A1 Moutarde, H. A1 Pène, O. A1 Rodríguez-Quintero, J. K1 Instanton K1 Lattice AB Gluon two- and three-point Green Functions computed in Landau gauge from the lattice show the existence of power corrections to the purely perturbative expressions, that can be explained through an Operator Product Expansion as the influence of a non gauge invariant mass dimension two condensate. The relationship of this condensate with topological properties of QCD, namely instantons, will be studied, giving a first estimate of the contribution of instantons to this condensate based in the direct lattice measure, after a cooling process, of the instanton liquid properties.
