Abstract

I present an overview of recent data on Deep Inelastic Scattering at large Bjorken x and low invariant mass, W², where parton-hadron duality was originally observed. I discuss the concept of parton-hadron duality from the perspective of perturbative QCD. Within this framework, I show that parton-hadron duality is broken for low values of W², in the $\Delta$- and S₁₁-resonance production region. A model that accounts for the anomalous scale dependence ensuing from this situation is developed.
