Calculating infrared contributions to vacuum expectation values of gluonic and quark fields

Based on the infrared asymptotics of the lower QCD Green's functions obtained before, we propose a definition and elaborate a technique for calculating non-perturbative vacuum expectations of gluon and quark fields. In our calculations, we use only the known QCD parameters: constitutent quark masses, the confining potential slope and the QCD parameter Γ. The values obtained for the vacuum expectations agree well with experiment.
