AB We present a lattice calculation of the renormalized running coupling constantin symmetric (MOM) and asymmetric (^MOM) momentum substraction schemes includingu, d, s and c quarks in the sea. An Operator Product Expansion dominated by thedimension-two hA2i condensate is used to fit the running of the coupling. We argue thatthe agreement in the predicted hA2i condensate for both schemes is a strong support forthe validity of the OPE approach and the effect of this non-gauge invariant condensateover the running of the strong coupling.
