Expressions for SO(4) invariant Euclidean QCD generating functionals are introduced which should produce nonvanishing gluon condensates. We consider first the loop expansion of corresponding effectíve action searching a description differing from usual perturbation theory. At this level, we special free propagators have off-diagonal long range order. The calculation polarization tensor leads to mass term is proportional squared root finite value <G 2 >. summation all one-loop contributions energy having only insertions, indicates spontaneous generation condensate perturbative ground state in way resembling similar effect case chromomagnetic field models.
