Description
The study of the nucleon excitation spectra allows to better understand
the dynamics of the constituents inside the nucleons and study quantum
chromodynamics (QCD) in the non-perturbative regime. Experimentally, the
nucleon excitation spectra can be investigated by studying different
meson photoproduction reactions. Partial wave analyses are performed in
order to extract the contributing resonances from experimental data. For
an unambiguous solution several single and double polarization
observables are needed. The CBELSA/TAPS experiment is located at the
electron stretcher accelerator ELSA in Bonn, Germany. It offers the
possibility to measure polarization observables with a linearly or
circularly polarized photon beam and a longitudinally or transversely
polarized target.
This talk will give an overview of recent CBELSA/TAPS results and the
future plans, which entail an upgrade of the existing experiment to the
INSIGHT (Investigation of the strong interaction in the light flavor
sector) experiment in order to study hyperons.
