Renormalon Model Predictions for Power-Corrections to Flavour Singlet Deep Inelastic Structure Functions

Abstract

We analyze power corrections to flavour singlet deep inelastic scattering structure functions in the framework of the infrared renormalon model. Our calculations, together with previous results for the non-singlet contribution, allow to model the x-dependence of higher twist corrections to F_2, F_L and g_1 in the whole x domain.
