Baryon spectrum and structure from first principles of QCD

### Speaker

### Description

The current status of the $\eta$ photoproduction analysis within the Jülich-Bonn framework is presented. A structure in production on the proton at around $W\sim 1.68$ GeV is discussed. Furthermore, the extraction of resonance helicity couplings and their correlations from $\eta$ photoproduction is outlined, and how new experiment could help to further disentangle these quantities. Also, a brief outlook is provided of how machine learning techniques can assist in determining the baryonic resonance spectrum from data.
