Power corrections to perturbative QCD and OPE in gluon green functions
We show that QCD Green functions in Landau Gauge exhibit sizable O(1/¿2) corrections to the expected perturbative behavior at energies as high as 10 GeV. We argue that these are due to a ¿A2¿-condensate which does not vanish in Landau gauge.
