(Vector) Meson Production and Duality
At high enough energies, hadronic cross sections, if averaged over an appropriate energy range, must coincide with a perturbative QCD description. One famous example in deep inelastic scattering is termed Bloom-Gilman duality. This quark-hadron duality shows that the nucleon resonance region closely mimics the deep inelastic region where we assume single quark scattering to be dominant. This Bloom-Gilman duality was recently found to work to high precision to far lower momentum transfers, and far smaller regions in invariant mass, than anticipated. Implications for using the spin/flavor selectivity of (polarized) electron-proton scattering and/or (polarized) meson electroproduction to examine such duality in more detail are discussed.
