Study of N(1520) and N(1535) structures via $$\gamma ^*p\rightarrow N^*$$ transitions

The helicity amplitudes of the $N(1520)$ and $N(1535)$ resonances in $\gamma^*p\to N^*$ electromagnetic transition are studied constituent quark model using impulse approximation, with proton assumed to be three-quark configurations. comparison theoretical results experimental data on $A_{1/2}$, $A_{3/2}$, $S_{1/2}$ indicates that primarily composed $L=1$ states but may contain additional components. However, it is improbable contributions from meson clouds will dominant at low $Q^2$.
