13 Dec 2002 | | Journal: | Few Body Syst.Suppl. 14 (2003) 411-414 | | Subject: | hep-ph | | Affiliation: | University of Graz, University of Pavia, University of Iowa | | Abstract: | Results for the proton and neutron electric and magnetic form factors as well as the nucleon axial form factor are presented for constituent quark models, based on either one-gluon-exchange and Goldstone-boson-exchange dynamics. The calculations are performed in a covariant framework using the point-form approach to relativistic quantum mechanics. The only input to the calculations is the nucleon wave function of the corresponding constituent quark model. A comparison is given to results of the instanton-induced constituent quark model treated with the Bethe-Salpeter equation. | | Source: | arXiv, hep-ph/0212190 | | Services: | Forum | Review | PDF | Favorites | |
