Power Corrections to Perturbative QCD and OPE in Gluon Green Functions
We show that QCD Green functions in Landau Gauge exhibit sizable $O(1/μ^2)$ corrections to the expected perturbative behavior at energies as high as 10 GeV. We argue that these are due to a $ $-condensate which does not vanish in Landau gauge.
