Partial wave analysis (PWA) is a key technique to extract resonances and their properties, such as quantum numbers, pole positions, and couplings to the different decay channels from experimental data. As such it is a prerequisite to reach a better understanding of the spectrum and the properties of hadrons. This project addresses, in close connection to the experiments and to the theory groups of this CRC, two topics, baryon- and meson-spectroscopy in the light-quark sector. Two different analysis tools are used, the Bonn-Gatchina (BnGa) PWA and the newly developed software package PAWIAN. Topics to be investigated are meson and baryon spectroscopy, in particular the analysis of photo- and electroproduction data off protons and neutrons, the Q2--dependence of helicity amplitudes as well as ψ‘ → baryon-antibaryon-meson decays. Also, the comparisons of the results obtained using the BnGa-PWA, PAWIAN or the JüBo approaches (B.11) will surely provide a deeper insight in the systematic differences of the physics obtained using different approaches.
