【 摘 要 】

Recent analyses of electromagnetic structure functions in the resonance region suggest that duality-violating higher twists are small above Q(sup 2) (approx) 1 GeV(sup 2). We review duality at the resonance--scaling transition, both phenomenologically and in the context of a simple quark model. While most studies have focused on electromagnetic probes, we also discuss expectations for the workings of duality in neutrino scattering. Finally, we describe the transition of the structure functions to the photoproduction limit at Q(sup 2)=0.
