Bethe-Salpeter equation with cross-ladder kernel in Minkowski and Euclidean spaces
arXiv:hep-th/0610158 · doi:10.1016/j.nuclphysa.2007.03.101
Abstract
Some results obtained by a new method for solving the Bethe-Salpeter equation are presented. The method is valid for any kernel given by irreducible Feynman graphs. The Bethe-Salpeter amplitude, both in Minkowski and in Euclidean spaces, and the binding energy for ladder + cross-ladder kernel are found. We calculate also the corresponding electromagnetic form factor.
