Abstract

The nonsinglet spin dependent structure function g2(x,Q2)g_2(x,Q^2) 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 power-like growth in 1/x1/x. We discuss how our result fits into the Wandzura-Wilczek relation.
