Nucleon electromagnetic form factors and electroexcitation of low lying
nucleon resonances in a light-front relativistic quark model    [PDF]

I. G. Aznauryan, V. D. Burkert

We utilize a light-front relativistic quark model (LF RQM) to predict the 3q
core contribution to the electroexcitation amplitudes for the Delta(1232)P33,
N(1440)P11, N(1520)D13, and N(1535)S11 up to Q2= 12GeV2. The parameters of the
model have been specified via description of the nucleon electromagnetic form
factors in the approach that combines 3q and pion-cloud contributions in the LF
dynamics.
