Abstract

We study the ladder Bethe-Salpeter (BS) equation on the light- front for two-bosons exchanging a third one. The kernel is constructed from the perturbative light-front propagator of the two-boson system up to O(g 4 s ). Intermediate states with up to four particles are considered. We compare the numerical solutions of the light-front and four-dimensional BS equations for the two-particle bound state mass and wave-function.
