Towards a combined analysis of inclusive/exclusive electroproduction

Abstract

In view of the major advances achieved by the CLAS experiments in studying the N* electroex citation amplitudes, as well as further extension of these studies in the experiments with CLAS12, we present an approach for the evaluation of the resonant contributions to inclusive electron scattering off protons. For the first time, the resonant contributions are determined from the experimental results on N* electrocouplings available from the data analyses of exclusive meson electroproduction off protons. This is a useful benchmark for future endeavours on understanding the transition region between low and high-energy regions, strongly related to tests on quark-hadron duality.

QCD, from its inception to its stubbornly unsolved problems

“…Is Bloom-Gilman duality 47,48 a prediction of QCD? In spite of recent efforts, 49 it is not (yet). That would require a complete understanding of bound-state production.…”
