1 Oct 2010 | Abstract: | We examine the nucleon’s electromagnetic form factors in a Poincare-covariant
Faddeev framework. The three-quark core contributions to the form factors are
obtained by employing a quark-diquark approximation. We implement the
self-consistent solution for the quark-photon vertex from its inhomogeneous
Bethe-Salpeter equation. We find that the resulting transverse parts which add
to the Ball-Chiu vertex have no significant impact on nucleon magnetic moments.
The current-quark mass evolution of the form factors agrees with results from
lattice QCD. | Source: | arXiv, 1010.0206 | Services: | Forum | Review | PDF | Favorites |
