BARYON FORM-FACTORS IN A DIQUARK QUARK BOUND-STATE DESCRIPTION

Nucleon form factors are calculated in a relativistic diquark-quark pi cture based on the Nambu-Jona-Lasinio model. The nucleon wave function is obtained in a static approximation to the quark exchange interacti on between the valence quark and the diquark. We evaluate the valence quark and 0(+)-diquark contribution to the nucleon electromagnetic and weak currents. We find reasonable electric charge radii, magnetic mom ents as in the additive diquark model, and g(A) approximate to 1. We d iscuss the dependence on the model parameters.
