Title: Nucleon resonance contributions to unpolarized inclusive electron scattering

Abstract

The first CLAS12 experiments will provide high-precision data on inclusive electron scattering observables at a photon virtuality Q² ranging from 0.05 to 12GeV² and center-of-mass energies W up to 4 GeV. In view of this endeavor, we present the modeling of the resonant contributions to the inclusive electron scattering observables. As input, we use the existing CLAS electrocoupling results obtained from exclusive meson electroproduction data off protons, and evaluate for the first time the resonant contributions based on the experimental results on the nucleon resonance electroexcitation. The uncertainties are given by the data and duly propagated through a Monte Carlo approach. In this way, we obtain estimates for the resonant contributions, important for insight into the nucleon parton distributions in the resonance region and for the studies of quark-hadron duality.

New Results on the Nucleon Resonance Spectrum and Structure from Photo- and Electroproduction Experiments

Conference Mokeev, Viktor

Studies of the excited nucleon (N*) spectrum and structure offer unique information on many facets of strong QCD dynamics in the generation of resonances of different quantum numbers. Advances in nucleon resonance studies in experiments with electromagnetic probes will be presented. Experimental studies of meson photoproduction off the nucleon at the JLab/CLAS, ELSA, and MAMI facilities have provided detailed information on all exclusive meson photoproduction channels relevant in the resonance region. Analyses of these data have considerably extended our knowledge of the N* spectrum. Several candidate N* states were included in the PDG as an outcome of these efforts withmore »« less

Nucleon Resonance Structure from Exclusive Meson Electroproduction with CLAS and CLAS12

Conference Philip L. Cole, Volker D. Burkert, Ralf W. Gothe, Victor I. Mokeev - Nuclear Physics B - Proceedings Supplements

The CLAS detector at Jefferson Lab is a unique instrument, which has provided the lion's share of the world's data on meson photo- and electroproduction in the resonance excitation region. The electroexcitation amplitudes for the low-lying resonances P{sub 33} (1232), P{sub 11} (1440), D{sub 13} (1520), and S {sub 11} (1535) were determined over a wide range of Q{sub 2} < 5.0 GeV{sub 2} in a comprehensive analysis of exclusive single-meson ( {pi}{sup +} n, {pi}{sup 0} p) reactions in the electroproduction off protons. Further, we were able to precisely measure {pi}{sup +}{pi}{sup -}p electroproduction differential cross sections provided bymore »« less

New opportunities for Insight into Emergence of Hadron Mass from Studies of Nucleon Resonance Electroexcitation

Conference Mokeev, Viktor

Understanding the emergence of hadron mass (EHM) represents one of the most challenging and still open problems in the Standard Model. Results of EHM studies from the nucleon resonance electroexcitation amplitudes (gvpN* electrocouplings) determined from exclusive meson electroproduction data measured with the CLAS detector will be presented in this talk. These CLAS data have provided the first and only available results on the evolution of the ?vpN* electrocouplings with photon virtuality Q2 up to 5 GeV2 for most nucleon resonances in the mass range up to 1.8 GeV. A successful description of the CLAS results on the Q2-evolution of themore »« less
Nucleon Resonance Structure from Exclusive Meson Electroproduction with CLAS

Journal Article Mokeev, Victor I. - Few-Body Systems

Studies of the nucleon resonance electroexcitation amplitudes in a wide range of photon virtualities offer unique information on many facets of strong QCD behind the generation of all prominent excited nucleon states of distinctively different structure. Advances in the evaluation of resonance electroexcitation amplitudes from the data measured with the CLAS detector and the future extension of these studies with the CLAS12 detector at Jefferson Lab are presented in this paper. For the first time, analyses ofmore »« less
