Perturbative QCD Analysis of Local Duality in a fixed W2 Framework
Description
We study the global Q2 dependence of large x, F2 nucleon structure function data, with the aim of providing a perturbative-QCD based, quantitative analysis of parton-hadron duality. As opposed to previous analyses at fixed x, we use a framework in fixed W2. We uncover a breakdown of the twist-4 approximation with a renormalon type improvement at O(1/Q4) which, by affecting the initial evolution of parton distributions, will have consequences for pQCD analyses also at large x and very large Q2
