“…For the resonances of the [70, 1 − ]-plet, the results for the transition amplitudes obtained with the wave functions (48,49) and corresponding parameters (51,52) are very close to each other. The role of the running quark mass becomes visible above 3 GeV 2 .…”

“…[13,49] the absolute values of the meson cloud contributions continued to the real axis and evaluated at W = 1.535, 1.52, and 1.675 GeV were determined for N (1520) − . Such pronounced peaks are also characteristic for the meson cloud contributions in the coupled-channels analyses [13,49,51,52]. Concerning the A 1/2 (Q 2 ) amplitude for the N (1520)…”

“…Much progress has been made recently within the EBAC/Argonne-Osaka coupled-channels analyses [13,49,50]. To date only preliminary results are available from the analyses that are based on the complete set of the CLAS pion electroproduction data in the entire Q 2 range up to 4.5 GeV 2 from the two channels ep → epπ 0 and ep → enπ + [51,52]. Results of the coupled-channels analyses are related to the resonance pole positions; with this in Refs.…”

We utilize the 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 neutron at Q 2 < 5 GeV 2 . The investigation is motivated by new experimental data from CLAS on meson electroproduction in a wide range of the hadronic invariant mass including the full third nucleon resonance region up to √ s = 1.8 GeV. − , experimental results on the electroexcitation amplitudes on the proton are available in a wide range of Q 2 . This allowed us also to quantify the expected meson-baryon contributions to these amplitudes as a function of Q 2 .
