Q^2 evolution of parton distributions at small x. A study of higher-twist effects

High Energy Physics - Phenomenology 2007-05-23 v1

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 excellent agreement with deep inelastic scattering experimental data from HERA.
