A6. Baryon resonances in a finite volume

U.-G. Meißner, A. Rusetsky

The project deals with the study of the resonance spectrum using effective field theories in a finite volume. In particular, we plan to investigate the electromagnetic form factor of the Delta-resonance, as well as the Delta-nucleon electromagnetic transition form factor. Further, the finite-volume approach will be applied to the multi-channel scattering case to study the properties of the Λ(1405) resonance. We also intend to carry out a full-fledged investigation of the three-body systems in a finite volume. The resulting framework will be used to analyze the lattice data for the Roper resonance.
