abstract = {We present a lattice calculation of the renormalized running coupling constant
in symmetric (MOM) and asymmetric (^MOM) momentum substraction schemes including
u, d, s and c quarks in the sea. An Operator Product Expansion dominated by the
dimension-two hA2i condensate is used to fit the running of the coupling. We argue that
the agreement in the predicted hA2i condensate for both schemes is a strong support for
the validity of the OPE approach and the effect of this non-gauge invariant condensate
over the running of the strong coupling.},
