Power Corrections to Perturbative QCD and OPE in Gluon Green Functions

Abstract

We show that QCD Green functions in Landau Gauge exhibit sizable $O(1/{\mu }^2)$ corrections to the expected perturbative behavior at energies as high as 10 GeV. We argue that these are due to a $<A^2>$-condensate which does not vanish in Landau gauge.
