Transition form factors and helicity amplitudes for electroexcitation of negative- and positive parity nucleon resonances in a light-front quark model

Igor T. Obukhovsky, Amand Faessler, Dimitry K. Fedorov +2

A workable basis of quark configurations $s^3$, $s^{2}p$ and $s{p}^2$ at light front has been constructed to describe the high-$Q^2$ behavior of transition form factors and helicity am…
