Abstract :
The QCD higher order effects to the polarized structure function g2(x,Q2) are renalyzed for massive quarks in the context of the operator product expansion. We confirm that the lowest moment of g2(x,Q2) which corresponds to the Burkhardt-Cottingham sum rule does not suffer from radiative corrections in perturbative QCD.
