Toward complete pion nucleon amplitudes

Year: 2015

Type: article

Abstract: We compare the low-energy partial-wave analyses of $\ensuremath{\pi}N$ scattering with high-energy data via finite-energy sum rules. We construct a new set of amplitudes by matching the imaginary part from the low-energy analysis with the high-energy, Regge parametrization and reconstruct the real parts using dispersion relations.
