Abstract
A framework of operator product expansion (OPE) allows us to study high-energy behaviour of Green functions. A calculation of such Green functions within chiral perturbation theory (chi PT) or resonance chiral theory (R chi T) and subsequent matching of the result to the OPE enables us to determine constraints for unknown parameters of the effective theories.
We present such procedure for Green functions in the odd-intrinsic parity sector of QCD.
