O(αs2) Corrections to Current Correlators
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 (m2/q2)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.
