Quark-hadron Duality: Resonances and the Onset of Scaling
نویسنده
چکیده
We examine the origin of Bloom-Gilman duality and the relationship between resonances and scaling in deep-inelastic scattering. A simple quantum mechanical model is used to illustrate the essential features of Bloom-Gilman duality at low momentum transfer. As an application of local duality, we discuss model-independent relations between structure functions at x ∼ 1 and elastic electromagnetic form factors.

Duality in Meson Electroproduction
We propose to study quark-hadron duality in meson electroproduction. While duality between inclusive electron-hadron scattering in the resonance and deep inelastic regimes (Bloom-Gilman or quark-baryon duality) is well established, the existence of a similar duality in meson electroproduction has not yet been tested. In the inclusive case, duality implies that single-quark scattering governs th...
متن کاملHigher Twists in the Pion Structure Function
We calculate the QCD moments of the pion structure function using DrellYan data on the quark distributions in the pion and a phenomenological model for the resonance region. The extracted higher twist corrections are found to be larger than those for the nucleon, contributing around 50% of the lowest moment at Q2 = 1 GeV2. Understanding the structure of the pion represents a fundamental challen...

The idea of quark-hadron duality is developed and applied to integral sum rules for the photoexcitation of meson resonances. Some applications of the presented approach in the light and heavy quark sectors are made, and the role of the scalar diquark cluster degrees of freedom in the radiative formation of light scalar mesons is discussed.

This experiment will extend measurements of inclusive nucleon resonance electropro-duction cross sections from hydrogen and deuterium targets throughout the resonance region (1 < W 2 < 4 GeV 2) to span the four-momentum transfer range 0.5 < Q 2 < 7.5 (GeV/c) 2. The cross sections will be used in conjunction with existing deep inelastic, resonance , and elastic data for precision experimental te...
متن کاملQuarks in the Bootstrap Era
The quark model emerged from the Gell-Mann–Ne’eman flavor SU(3) symmetry. Its development, in the context of strong interactions, took place in a heuristic theoretical framework, referred to as the Bootstrap Era. Setting the background for the dominant ideas in strong interaction of the early 1960s, we outline some aspects of the constituent quark model. An independent theoretical development w...
