Abstract

The twist--2 heavy flavor contributions to the polarized structure function g2(x,Q2)g_2(x,Q^2) are calculated. We show that this part of g2(x,Q2)g_2(x,Q^2) is related to the heavy flavor contribution to g1(x,Q2)g_1(x,Q^2) by the Wandzura--Wilczek relation to all orders in the strong coupling constant. Numerical results are presented.
