Determination of resonance couplings and high energy amplitudes in γN --> πN using fixed-t dispersion relations
TL;DR: In this paper, the real parts of the amplitudes are generated entirely from their imaginary parts via d.rs., and essentially all available data is included at all energies with momentum transfer | t | 2.

Positive and neutral pion photoproduction analysis
TL;DR: In this article, a covariant scattering amplitude is written down including Born terms without multipole projections, pion-nucleon isobars and two-part bipion contribution, and a satisfactory fit is obtained from threshold to 800 MeV.

Photoproduction of pi o from hydrogen near the second pion nucleon resonance
TL;DR: In this article, the authors used the Stanford Mark III linear accelerator to study the second pion-nucleon resonance and showed that the discrepancy in resonance positions is not due to the photo-electric term, but rather due to crossed nucleon and nucleon isobar exchanges.
