Small-x behavior of the nonsinglet polarized structure function g2 in the double logarithmic approximation
Abstract
The nonsinglet spin dependent structure function g2(x,Q2) is studied at small x within the double logarithmic approximation of perturbative QCD. Both positive and negative signature contributions are considered, and we find a powerlike growth in 1/x. We discuss how our result fits into the Wandzura-Wilczek relation.
