Gluon Contribution to the Transverse Spin Structure Function g2

Abstract

We consider the twist-3 gluon contribution to the transverse spin structure function $g_2$.We find that the Burkhardt-Cottingham sum rule is satisfied. The additional {\it nonlocal} operators appear in the moments of g2 which were absent in previous analysis of Bukhvostov, Kuraev and Lipatov.
