Nucleon and hyperon electromagnetic structure

We report on new investigations of the electromagnetic structure of the nucleons as well as other octet and decuplet baryons within relativistic constituent quark models. First we discuss predictions of the one-gluon-exchange and Goldstone-boson-exchange constituent quark models for charge radii and magnetic moments calculated in point form. Then we make a comparison of the point form to the instant form through completely analogous calculations of the nucleon electromagnetic form factors in the spectator model of the electromagnetic current. Huge differences are found between the pertinent predictions.
