On baryon properties from a covariant Faddeev approach

Abstract

The Poincare-covariant Faddeev equation and its solution in rainbow-ladder truncation, i.e., with a generalized gluon exchange as irreducible two-particle-interaction, is presented. The covariant decomposition of baryon amplitudes, representing relativistic three-quark states, is discussed and explicitly given for the Delta-baryon. The calculated Delta mass compares favourably with the experimental one.
