B.7 Coupled channels approach to photo-meson production on the nucleon
H. Lenske
The partial wave analysis of meson production on the nucleon, based on a Lagrangian formulation will be continued. Photo- and hadron-induced production processes are described simultaneously by a coupled channels T-matrix approach in s-, t- and u-channels. In the next funding period the major tasks will be to complete and implement two-meson dynamics and to explore the connection to QCD-inspired Dyson-Schwinger descriptions. Large scale partial wave analyses are envisaged, focusing on polarization observables and non-pionic and multi-meson production scenarios.
