摘要：We present a calculation of the three-quark core contribution to the mass of the D-resonance in a
Poincaré-covariant Faddeev framework. A consistent setup for the dressed-quark propagator, the
quark-quark and quark-’diquark’ interactions is used, where all the ingredients are solutions of
their respective Dyson-Schwinger or Bethe-Salpeter equations in rainbow-ladder truncation. We
discuss the evolution of the D mass with the current-quark mass and compare to the previously
obtained mass of the nucleon.
