摘要

In this contribution three-loop QCD corrections to current correlators are considered. The application of the large momentum procedure, which provides a systematic expansion in $(m^2/q^2)^n$ , allows the computation of terms up to $n=6$ for the vector and axial-vector correlator and up to $n=4$ for the scalar and pseudo-scalar correlator. Some physical applications are discussed.
