Remarks on the determination of the Landau gauge OPE for the asymmetric three gluon vertex -: art. no. 114003

We compute a compact operator Product expansion (OPE) formula describing power corrections to the perturbative expression for the asymmetric momentum substraction - (MOM) renormalized running coupling constant LIP to the leading, logarithm. By the use of a phenomenological hypothesis leading to the factorization of the condensates though a perturbative vacuum insertion. the only relevant condensate in the game is (A(2)). The validity of the OPE formula is tested by searching for a good-quality coherent description of previous lattice evaluations of the MOM-renormalized gluon propagator and running coupling.
