Photocouplings at the pole from pion photoproduction
Photocouplings at the pole from pion photoproduction
The reactions γp→π0p and γp→π+n are analyzed in a semi-phenomenological approach up to E∼2.3 GeV. Fits to differential cross section and single and double polarization observables are performed. A good overall reproduction of the available photoproduction data is achieved. The J\"ulich2012 dyna...

The reactions γp→π0p and γp→π+n are analyzed in a semi-phenomenological approach up to E∼2.3 GeV. Fits to differential cross section and single and double polarization observables are performed. A good overall reproduction of the available photoproduction data is achieved. The J\"ulich2012 dynamical coupled-channel model -which describes elastic πN scattering and the world data base of the reactions πN→ηN, KΛ, and KΣ at the same time - is employed as the hadronic interaction in the final state. The framework guarantees analyticity and, thus, allows for a reliable extraction of resonance parameters in terms of poles and residues. In particular, the photocouplings at the pole can be extracted and are presented. |
