TL;DR
This paper updates the partial-wave analysis of nucleon-nucleon elastic scattering data up to 3 GeV, incorporating recent measurements, especially from COSY, to refine understanding of scattering amplitudes.
Contribution
It provides an updated analysis including new experimental data, enhancing the accuracy of NN elastic scattering models above 1 GeV.
Findings
Significant impact of recent COSY measurements on analysis
Refined partial-wave and direct-reconstruction amplitudes
Improved understanding of NN scattering at energies above 1 GeV
Abstract
A partial-wave analysis of NN elastic scattering data has been updated to include a number of recent measurements. Experiments carried out at the Cooler Synchrotron (COSY) by the EDDA Collaboration have had a significant impact above 1 GeV. Results are discussed in terms of the partial-wave and direct-reconstruction amplitudes.
