| Title | First Results on Nucleon Resonance Electroexcitation Amplitudes from ep -> e' pi+ pi- p' Cross Sections at W from 1.4-1.7 GeV and Q2 from 2.0-5.0 GeV2 | ||||
| Abstract | The electroexcitation amplitudes or gamma_vpN electrocouplings of the N(1440)1/2+, N(1520)3/2-, and Delta(1600)3/2+ resonances were obtained for the first time from the ep to e' pi+ pi- p' differential cross sections measured with the CLAS detector at Jefferson Lab within the range of invariant mass W of the final state hadrons from 1.4-1.7 GeV for photon virtualities Q2 from 2.0-5.0 GeV2. A good description of the nine independent one-fold differential gamma_vp to pi+ pi- p' cross sections achieved within the data-driven JM meson-baryon reaction model in each bin of (W,Q2) allows for separation of the resonant and non-resonant contributions. The electrocouplings were determined in independent fits of the pi+ pi- p cross sections within three overlapping W intervals with a substantial contribution from each of the three resonances listed above. Consistent results on the electrocouplings extracted from the data in these W intervals provide evidence for their reliable extraction. These s | ||||
