Photoproduction of pions and properties of baryon resonances from a Bonn-Gatchina partial wave analysis

Abstract

Masses, widths and photocouplings of baryon resonances are determined in a coupled-channel partial wave analysis of a large variety of data. The Bonn-Gatchina partial wave formalism is extended to include a decomposition of t- and u-exchange amplitudes into individual partial waves. The multipole transition amplitudes for $\gamma p\to p{\pi }^0$ and $\gamma p\to n{\pi }^{+}$ are given and compared to results from other analyses.
