Description
We review the study the Wandzura--Wilczek relation for the structure function g2, with a particular attention on the connection with the framework of Transverse Momentum Dependent factorization. We emphasize that the relation is broken by two distinct twist-3 terms. In the light of these findings, we clarify what can be deduced from the available experimental data on g2, which indicate a breaking of the order 20-40%, and how to individually measure the twist-3 terms.
