Journal of High Energy Physics. Vol. 2014, n. 4, (2014). ISSN 1029-84791029-8479http://hdl.handle.net/10272/10492We 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.engAn error occurred on the license name.An error occurred getting the license - uri.Lattice QCDSum RulesQCDjournal article10.1007/JHEP04(2014)086open access
