Abstract

We present a numerical study of twist-four corrections to the deep inelastic structure function F2 at small x and small Q2. The calculations are based upon the double logarithmic approximation of the coupled twist-four evolution equations of those gluonic twist-four operators that are dominant at small x. We show, for two different assumptions on the x-dependence of the input distributions, the relative magnitude of the leading-twist and the twist-four contribution.
