Delta and Omega electromagnetic form factors in a Dyson-Schwinger/Bethe-Salpeter approach

Understand

We investigate the electromagnetic form factors of the Delta and the Omega baryons within the Poincare-covariant framework of Dyson-Schwinger and Bethe-Salpeter equations.

• The three-quark core contributions of the form factors are evaluated by employing a quark-diquark approximation.
• We use a consistent setup for the quark-gluon dressing, the quark-quark bound-state kernel and the quark-photon interaction.
• Our predictions for the multipole form factors are compatible with available experimental data and quark-model estimates.
