Renormalon model predictions for power corrections to flavor-singlet deep-inelastic structure functions Original Research Article

We analyze power corrections to flavor-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 us to model the x-dependence of higher twist corrections to F2, FL and g1 in the whole x domain.
