Description

The small-x behavior of the singlet contributions to the polarized structure function g2(x,Q2) is calculated in the double-logarithmic approximation of perturbative QCD. The dominant contribution is due to the gluons which, in contrast with the unpolarized case, mix with the fermions also in the small-x domain. We find a powerlike growth in 1/x in the odd-signature parts of the amplitude with the same power as in the singlet function g1(x,Q2) at x<<1
