Ghost and Gluon leading power corrections in Landau gauge
Résumé
Gluon two- and three-point Green Functions computed in Landau gauge on the lattice have shown the existence of 1/q2 power corrections to the purely perturbative expressions that can be explained through the Operator Product Expansion as the influence of a gauge dependent mass dimension two condensate. The analysis of the ghost propagator within this framework of gauge-dependent power corrections is now performed.
