Analysis of new polarization data in pion photoproduction

New measurements by the CBELSA/TAPS collaboration of the polarization observables T, E, P, G, and H in γp → π0p were included in the coupled-channels JüBo fits.

Solution Jülich2013:

Photocouplings at the pole from pion photoproduction

Photocouplings at the pole are extracted from a combined analysis of the reactions γp → π0p and γp → π+n. The Jülich2012 dynamical coupled-channel model is employed as the hadronic final-state interaction. [please refer to Eur. Phys. J. A50 (2014) 101]

Solution Jülich2012:

Coupled-channel dynamics in the reactions πN → πN, ηN, KΛ, KΣ

Elastic πN scattering and the reactions π-p → ηn, K0Λ, K0Σ0, K+Σ- and π+p → K+Σ+ are analyzed simultaneously and the resonance content in terms of pole positions and residues is determined. [please refer to Eur. Phys. J. A49 (2013) 44]


Partial wave amplitudes of the Jülich2012 solution:

For each partial wave L2I2J the partial wave amplitudes τ for fit A and B are given in the table below, for all on-shell transitions among the channels πN, ηN, KΛ, KΣ.
The ordering of the columns of the individual tables ( L2I2J.txt files) is defined in this comment .
