Description

Electromagnetic Form factors give information on internal dynamics of hadrons. They are
theoretical input to the hadron electromagnetic current in calculation of the structure of
hadrons. Their direct measurement in the spacelike and timelike kinematic regime,
respectively, is made through differential cross sections and polarization observables of
electron scattering and electron-positron annihilation reactions. In this talk I review on how
a variety of recent experimental data on low-lying nucleon resonance electromagnetic
excitations can tell us about the evolution of the relevant degrees of freedom and the
photon-baryon couplings. The importance of multiquark meson-baryon decay channels and
meson-cloud configurations is addressed within a relativistic quark model calculation.
