Electroexcitation of nucleon resonances of the [70,1-] multiplet in a light-front relativistic quark model
Inna Aznauryan, Volker Burkert
We utilize a light-front relativistic quark model to predict the 3q core contribution to the electroexcitation of nucleon resonances of the [70,1-] multiplet on the proton and neut…
Extracting meson-baryon contributions to the electroexcitation of the nucleon resonance
I. G. Aznauryan, V. D. Burkert
We report on the determination of the electrocouplings for the transition from the proton to the resonance state using recent differential cross section da…
Studies of Nucleon Resonance Structure in Exclusive Meson Electroproduction
I. G. Aznauryan, A. Bashir, V. Braun +24
Studies of the structure of excited baryons are key to the N* program at Jefferson Lab. Within the first year of data taking with the Hall B CLAS12 detector following the 12 GeV up…
Extraction of P11 Resonance from pi-N Data and Its Stability
S. X. Nakamura, H. Kamano, T. -S. H. Lee +1
An important question about resonance extraction is how much resonance poles and residues extracted from data depend on a model used for the extraction, and on the precision of dat…
Electroexcitation of the Roper resonance from CLAS data
Inna Aznauryan, Volker Burkert
The helicity amplitudes of the electroexcitation of the Roper resonance on proton are extracted at 1.7 < Q2 < 4.2 GeV2 from recent high precision JLab-CLAS cross sections data and…
Electroexcitation of the P33(1232), P11(1440), D13(1520), S11(1535) at Q^2=0.4 and 0.65(GeV/c)^2
I. G. Aznauryan, V. D. Burkert, H. Egiyan +3
Using two approaches: dispersion relations and isobar model, we have analyzed recent high precision CLAS data on cross sections of π^0, π^+, and ηelectroproduction on protons, and…
Probing the Structure of Nucleons in the Resonance Region
Volker D. Burkert
Status, open questions, and future prospects of the physics of excited nucleons are discussed. Emphasis is on the study of the structure of nucleons via measurements of their elect…
Generalized Gerasimov-Drell-Hearn Sum Rule for the Proton-Neutron Difference in Chiral Perturbation Theory
Volker D. Burkert
Applications of the chiral expansion to generalize the Gerasimov-Drell-Hearn sum rule for finite are discussed. The observation of several authors that the corrections to the…
Recent Results from Jefferson Lab
Volker D. Burkert
Recent results on studies of the structure of nucleons and nuclei in the regime of strong interaction QCD are discussed. Use of high current polarized electron beams, polarized tar…
