Extended partial-wave analysis of π N scattering data
TL;DR: In this article, a coupled-channel formalism was employed to simultaneously fit elastic scattering and charge-exchange data to 0.8 GeV and 2.6 GeV in the lab pion kinetic energy.
Updated analysis of NN elastic scattering to 3-GeV
TL;DR: In this article, a partial-wave analysis of elastic scattering data has been updated to include a number of recent measurements, including experiments carried out at the Cooler Synchrotron (COSY) by the EDDA Collaboration have had a significant impact above 1 GeV.

Nucleon-nucleon elastic scattering to 3 GeV
Abstract: A partial-wave analysis (PWA) of NN elastic scattering data has been completed. This analysis covers an expanded energy range, from threshold to a laboratory kinetic energy of 3 GeV, in order to include recent elastic pp polarized scattering measurements performed at SATURNE II. Results of the energy-dependent fit are compared with single-energy solutions and Saclay amplitudes obtained via the direct-reconstruction approach. We also comment on the status of {epsilon}{sub 1} in the low-energy region. (c) 2000 The American Physical Society.

Parameterization dependence of T matrix poles and eigenphases from a fit to $\pi$N elastic scattering data
TL;DR: In this article, the authors compare fits to piN elastic scattering data, based on a Chew-Mandelstam K-matrix formalism, and find that the locations of most poles are relatively stable.
