Covariant nucleon electromagnetic form factors from the Goldstone-boson-exchange quark model

We present a study of pro ton and neutron electromagnetic form factors for the recently proposed Goldstone-boson-exchange constituent quark model. Results for charge radii, magnetic moments, and electric as well as magnetic form factors are reported. The calculations are performed in a covariant framework using the point-form approach to relativistic quantum mechanics. All the predictions by the Goldstone-boson-exchange constituent quark model are found to fall remarkably close to existing experimental data. (C) 2001 Elsevier Science B.V. All rights reserved.
