Twist-2 Heavy Flavor Contributions to the Structure Function $g_{2} (x, Q^{2})$

arXiv:hep-ph/0304292 · doi:10.1103/PhysRevD.68.114004

Abstract

The twist--2 heavy flavor contributions to the polarized structure function $g_{2} (x, Q^{2})$ are calculated. We show that this part of $g_{2} (x, Q^{2})$ is related to the heavy flavor contribution to $g_{1} (x, Q^{2})$ by the Wandzura--Wilczek relation to all orders in the strong coupling constant. Numerical results are presented.
