Relativistic bound-state calculations in Light Front Dynamics

Abstract

We calculated bound states in the quantum field theoretical approach. Using the Wick-Cutkosky model and an extended version of this model (in which a particle with finite mass is exchanged) we have calculated the bound states in the scalar case.Comment: 3 pages, proceedings of the Light Cone Meeting Trento 2001, to be published in Nucl.
