Electroexcitation of nucleon resonances of the [70,1-] multiplet in a light-front relativistic quark model

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 GeV2. The investigation is motivated by new experimental data from continuous electron beam accelerator facility large acceptance spectrometer on meson electroproduction for a wide range of the hadronic invariant mass including the full third nucleon resonance region up to root s = 1.8 GeV. For the states N(1520)3/2(-), N(1535)1/2(-), and N(1675)5/2(-), experimental results on the electroexcitation amplitudes on the proton are available for 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).
