Abstract

The status of the electro-excitation program to study baryon resonances at Jefferson Lab will be exemplified by the most recent results on resonance parameters and transition form factors in single and double-pion production. These results demonstrate that the separation of resonance and background contributions and therefore the extraction of the electro-coupling amplitudes of resonances become easier and cleaner at higher four-momentum transfers (Q2). Furthermore, the double-pion in comparison to the single-pion channel shows a higher sensitivity to higher excited resonances and a distinctly different Q2 dependence of the background amplitudes. The combined analysis of the single- and double-pion data reduces model dependent uncertainties significantly, which allows us to extract the resonant electrocoupling amplitudes with an unprecedented quality.

Hadron Spectroscopy at CLAS and the Evolution of Strong Degrees of Freedom

Conference Gothe, R.

Understanding the strong force constitutes one of the biggest challenges in fundamental science that we can and have to tackle now as the needed experimental and theoretical tools become available. Perturbative Quantum ChromoDynamics (pQCD) at small distances, which is governed by quark and gluon fields, and Chiral Perturbation Theory (ChPT) at larger distances, which is governed by pion fields, are both already experimentally validated. However, strong fields at intermediate distances, where they generate about 98% of the total mass of nucleons and therefore of all normal matter, are not understood on similarly firm grounds. Electron scattering in particular serves asmore »« less

Nucleon resonance electrocouplings in the non-perturbative regime

Conference

There is an extensive search for baryon resonances using the CLAS detector in Hall B of JLab. Extracting the transition helicity amplitudes (or the {gamma}{sub v}NN* photo- and electrocouplings) sheds light on nature of the non-perturbative strong interaction. We have extended the data on differential cross sections to Q{sup 2} = 6.0 GeV{sup 2} for the {pi}N electroproduction channel. Electroproduction data were also collected on the two-charged-pion channel off protons, which provides nine independent differential {pi}{sup +}{pi}{sup -}p cross sections at Q{sup 2} up to 1.5 GeV{sup 2}. The two-pion results, moreover, are consistent with those from independent {pi}N electroproductionmore »« less
Electroproduction of Excited Baryons with the CLAS Detector in Hall B of Jefferson Lab

Conference

Recent results from Jefferson Lab (JLab) on the extraction of single–and double-polarization observables in both the 1pi–and 2pi-channel show their high sensitivity to resonant production amplitudes and therefore their importance for the extraction of resonance parameters. The CEBAF Large Acceptance Spectrometer (CLAS) has access to the baryon resonance (N*) form factors at high Q2, which is advantageous for the study of the dynamical properties of nucleon resonances. In anticipation of the 12 GeV energy upgrade to JLab, our group plans to extract the electromagnetic transition form factors (electrocouplings) for many well-established excited nucleon states in the unexplored domain of Q2>5more »« less

Nucleon Resonance Structure from Exclusive Meson Electroproduction with CLAS and CLAS12

Conference

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

Transition Form Factors: A Unique Opportunity to Connect Non-Perturbative Strong Interactions to QCD

Conference Gothe, Ralf - International Journal of Modern Physics: Conference Series

Meson-photoproduction measurements and their reaction-amplitude analyses can establish more sensitively, and in some cases in an almost model-independent way, nucleon excitations and non-resonant reaction amplitudes. However, to investigate the strong interaction from explored — where meson-cloud degrees of freedom contribute substantially to the baryon structure — to still unexplored distance scales — where quark degrees of freedom dominate and the transition from dressed to current quarks occurs — we depend on experiments that allow us to measure observables that are probing this evolving non-perturbative QCD regime over its full range. Elastic and transition form factors are uniquely suited to tracemore »« less
