Asymptotical small-x behaviour of the spin structure functions g_1 and g_2

Abstract

We show that for small x and in the double logarithmic approximation (DLA) g_2 can be expressed through derivative of g_1 with respect to logarithm of the QCD coupling. Therefore the small-x behavior of the both structure functions is similar. The analytical expression for flavor nonsinglet structure function g_1 is presented and its asymptotical behaviour is calculated.
