HIGHER TWIST OPERATOR EFFECTS TO PARTON DENSITIES AT SMALL X
/ Authors
/ Abstract
We investigate the Q^2 evolution of parton distributions at small x values, obtained in the case of flat initial conditions. The contributions of twist-two and (renormalon-type) higher-twist operators of the Wilson operator product expansion are taken into account. The results are in very good agreement with deep inelastic scattering experimental data from HERA.
