Abstrakt
A study of high-energy behavior of the three-point Green functions of chiral currents within the framework of the operator product expansion (OPE) is presented. In detail, we introduce an expansion of such correlators in terms of the QCD condensates up to dimension six.
Next, we discuss some specifics of matching the OPE with calculations of the correlators within the chiral perturbation theory and resonance chiral theory, which can lead to important constraints of the coupling constants of the chiral/resonance Lagrangian.
