More on the Burkhardt-Cottingham Sum Rule in QCD

Abstract

The QCD higher order effects to the polarized structure function $g_2(x,Q^2)$ are reanalyzed for massive quarks in the context of the operator product expansion. We confirm that the lowest moment of $g_2(x,Q^2)$ which corresponds to the Burkhardt-Cottingham sum rule does {\sl not} suffer from radiative corrections in perturbative QCD.
