“…Indeed, in the context of the RG, considering models which are small perturbations of the free field, the generating function of field correlations and the correlations can be obtained through a formula which involves the effective actions generated applying the RG transformations to the partition function (see e.g. [13]). However, unfortunately, in the case of gauge fields, this question, as well as the incorporation of fermion fields and the verification of the Osterwalder-Schrader-Seiler axioms [4], have never been completely analyzed up to now, for d = 4.…”
