A6. Baryon-Resonanzen im endlichen Volumen

U.-G. Meißner, A. Rusetsky

In diesem Projekt wird das Resonanzspektrum im endlichen Volumen, basierend auf Methoden der effektiven Feldtheorie, studiert. Die elektromagnetischen Formfaktoren der Delta-Resonanz und die Delta-Nukleon Übergangs-Formfaktoren sollen analysiert werden. Weiterhin soll der Mehrkanal-Fall zur Extraktion der Λ(1405) Resonanz studiert werden sowie das 3-Teilchen System im endlichen Volumen zur Extraktion der Roper-Resonanz aus Gittersimulationen.
