Abstract
At high enough energies asymptotic freedom guarantees the deep inelastic scattering cross sections to be calculated as nearly free electron-quark scattering. However, confinement guarantees that the experimentally observed final states particles are hadrons. Low-energy quark hadron duality suggests that the hadronic cross sections, when averaged over an appropriate energy range, nevertheless coincide with the naive leading-twist quark-gluon calculations. Deep inelastic inclusive scattering shows that scaling at modest Q{sup 2} and v already arises from very few resonance channels. This is reflected by the striking agreement ( 4GeV{sup 2}) region for the Q{sup 2}>0.5 (GeV/c){sup 2}, known as the Bloom-Gilman duality. Electron-hadron scattering allows for further investigation of quark-hadron duality by virtue of its ability to select resonances, by tagging with either spin or flavor.
