Binding Energy in Two and Three-Body Relativistic Dynamics

Abstract

Two-body and three-body systems of scalar bosons are considered in the framework of covariant constraint dynamics. The reduced equation obtained after eliminating redundant degrees of freedom can be viewed as an eigenvalue equation for an observable which is intimately related with the relative motion. We display the connection of this observable with binding energy.Comment: 12 pages, LaTeX. Talk presented at the Workshop "Critical Stability of Few-Body Quantum Systems", Les Houches Oct. 8-12, 200
