The Fundamental Scale of QCD

There are several scales in the QCD as theory of strong interaction: vacuum gluonic condensate (as divergence dilatation current), nucleon mass basic scale our universe, which is connected to string tension $\sigma$, and perturbative $\Lambda_{\rm QCD}$, defines renormalized expansions. In this paper we connect all these condensate, using field correlator method, where expressed terms nonlocal correlators, local condensates, while $\Lambda_V$ $\sigma$ framework Background Perturbation Theory (BPT). We also demonstrate how IR singularities renormalons disappear BPT making resulting internally consistent.
