Abstract

We present a calculation of the three-quark core contribution to nucleon and Δ-baryon masses and Δ electromagnetic form factors in a Poincaré-covariant Faddeev approach. A consistent setup for the dressed-quark propagator, the quark–quark, quark–’diquark’ and quark–photon interactions is employed, where all ingredients are solutions of their respective Dyson–Schwinger or Bethe–Salpeter equations in a rainbow-ladder truncation. The resulting Δ electromagnetic form factors concur with present experimental and lattice data.
