Title: New results from the studies of the Ν (1440) 1/2⁺, Ν (1520) 3/2^–, and Δ (1620) 1/2^– resonances in exclusive ep → e'p'π⁺π^– electroproduction with the CLAS detector

Abstract

In this study, the transition helicity amplitudes from the proton ground state to the N(1440)1/2⁺, N(1520)3/2^–, and Δ(1620)1/2^– resonances (γvpN* electrocouplings) were determined from the analysis of nine independent onefold differential π⁺π^–p electroproduction cross sections off a proton target, taken with CLAS at photon virtualities 0.5GeV² < Q² < 1.5 GeV². The phenomenological reaction model employed for separation of the resonant and nonresonant contributions to this exclusive channel was further developed.

Experimental study of the P₁₁(1440) and D₁₃(1520) resonances from the CLAS data on ep→e^'π⁺π⁻p^'

Journal Article Mokeev, V. I. ; Burkert, V. D. ; Elouadrhiri, L. ; ... - Physical Review. C, Nuclear Physics

The transition helicity amplitudes from the proton ground state to the P₁₁(1440) and D₁₃(1520) excited states (γ_vpN* electrocouplings) were determined from the analysis of nine independent one-fold differential π⁺π⁻p electroproduction cross sections off a proton target, taken with CLAS at photon virtualities of 0.25<0.60 GeV². The phenomenological reaction model was employed for separation of the resonant and nonresonant contributions to the final state. The P₁₁(1440) and D₁₃(1520) electrocouplings were obtained from the resonant amplitudes parametrized within the framework of a unitarized Breit-Wigner ansatz. They are consistent with results obtained in the previous CLAS analyses of the π⁺n and π⁰p channels.more »« less

Nucleon Resonance Structure from Exclusive Meson Electroproduction with CLAS and CLAS12

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.

Journal Article Aznauryan, I G ; Burkert, V D ; Egiyan, H ; ... - Physical Review. C, Nuclear Physics

Using two approaches - dispersion relations and the isobar model - we have analyzed recent high precision CLAS data on cross sections of {pi}{sup 0}, {pi}{sup +}, and {eta} electroproduction on protons, and the longitudinally polarized electron beam asymmetry for p(e{sup {yields}},e{sup '}p){pi}{sup 0} and p(e{sup {yields}},e{sup '}n){pi}{sup +}. The contributions of the resonances P{sub 33}(1232), P{sub 11}(1440), D{sub 13}(1520), and S{sub 11}(1535) to {pi} electroproduction and of S{sub 11}(1535) to {eta} electroproduction are found. The results obtained using the two approaches are in good agreement. There is also good agreement between amplitudes of the {gamma}*N{yields}S{sub 11}(1535) transition found inmore »« less
