Bethe-Salpeter equation in Minkowski space with cross-ladder kernel
arXiv:nucl-th/0510051 · doi:10.1016/j.nuclphysbps.2006.08.068
Abstract
A new method for solving the Bethe-Salpeter equation is developed. It allows to find the Bethe-Salpeter amplitudes both in Minkowski and in Euclidean spaces and, as a by product, the light-front wave function. The method is valid for any kernel given by irreducible Feynman graphs. Bethe-Salpeter and Light-Front equations for scalar particles with ladder + cross-ladder kernel are solved.
