An Instanton Picture O.P.E. (A2) Condensate?

Boucaud, Ph.; De Soto, F.; Donini, A.; Rodríguez Quintero, José (Elsevier, 2003-05)

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 ...
Instantons and the A (2) condensate

Boucaud, Ph.; Leroy, J. P.; Le Yaouanc, Alain; Micheli, J.; Pène, O.; Soto Borrero, Feliciano Carlos de; Donini, A.; Moutarde, Hervé; Rodríguez Quintero, José (American Physical Society, 2002)

We argue that the ⟨A2OPE⟩ condensate found in the Landau gauge on lattices, when an operator product expansion of Green’s functions is performed, might be explained by instantons. We use cooling to estimate the instanton ...
