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.
