Description

Investigating the baryon excitation spectrum is essential for understanding the internal dynamics of baryons and quantum chromodynamics (QCD) in the non-perturbative regime. Experimentally, the baryon spectrum can be probed with a real photon beam in photoproduction reactions. Partial wave analyses are performed to extract the baryon resonance parameters from the experimental data. For an unambiguous solution, the measurement of several single and double polarization observables is crucial.
The CBELSA/TAPS experiment at the accelerator facility ELSA in Bonn has a dedicated program towards measuring a large set of polarization observables in many different photoproduction reactions using polarized photon beams and polarized targets. The detector setup is excellent at measuring neutral mesons in the final states, using electromagnetic calorimeters that cover almost the full solid angular range. This talk will give an overview about recent results in non-strange baryon spectroscopy at ELSA.
