Abstract
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 , allows the computation of terms up to for the vector and axial-vector correlator and up to for the scalar and pseudo-scalar correlator. Some physical applications are discussed.
