The relativistic three-body problem and its stability on the light front — •S. Mattiello¹, M. Beyer¹, T. Frederico², and H.J. Weber³ — ¹FB Physik, U Rostock, Germany — ²CTA, Sao Jose dos Campos, Brazil — ³U of Virginia, Charlottesville, USA

We present a relativistic three-body equation to study the stability of the isolated three-body system with a zero-range force. Relativity is implemented utilizing the light front form. In particular we study the dependence of the system on an invariant cut-off. This can be understood as the limiting scale for physics beyond “zero-range approximation” or as an effective size parameter. The conditions of the relativistic Thomas collapse are discussed. We investigate the possibility to describe the nucleon as a Borromean system.
