We work in the Yukawa model and first calculate the bound-state equation in the ladder approximation. We discuss why this is not a complete treatment and what possibilities there are to extend this equation.Proceedings of the international workshop on: Light Cone Physics: Hadrons and Beyond, Durham (UK), August 5th-9th 2003High Energy Physics - Phenomenologytext
