Nucleon spin decomposition at twist three

arXiv:1308.4836 · doi:10.1142/S2010194514600325

Abstract

I review the recent progress in understanding the complete gauge invariant decomposition of the nucleon spin with particular emphasis on its twist structure.

8 pages; to appear in the proceedings of `QCD evolution workshop 2013', Jefferson lab, May 6-10
