Abstract
We discuss the extension of a systematic perturbative QCD based analysis to the x -> 1 region. After subtracting a number of effects that transcend NLO pQCD evolution, such as target mass corrections and large x resummation effects, the remaining power corrections can be interpreted as dynamical higher twists. The quantitative outcome of the analysis is dominated by the interplay between the value of alpha_S in the infrared region and the higher twists. We uncover a dual role played by alpha_S at large Bjorken x that can be used to experimentally extract its value in the non-perturbative regime.
