O(\alpha_s^2) Corrections to Current Correlators

High Energy Physics - Phenomenology 2007-05-23 v1

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(m^2/q^2)^n, allows the computation of terms up to n=6n=6 for the vector and axial-vector correlator and up to n=4n=4 for the scalar and pseudo-scalar correlator. Some physical applications are discussed.
