Updated SAID analysis of pion photoproduction data
arXiv:1109.0722 · doi:10.1103/PhysRevC.85.025201
Abstract
Energy-dependent and single-energy fits to the existing pion photoproduction database have been updated to cover the region from threshold to 2.7 GeV in the laboratory photon energy. Revised resonance photo-decay couplings have been extracted and compared to previous determinations. The influence of recent measurements is displayed. Remaining problems and future approaches are discussed.
