Partial-Wave Analysis of Nucleon-Nucleon Elastic Scattering Data

Understand

Energy-dependent and single-energy fits to the existing nucleon-nucleon database have been updated to incorporate recent measurements.

• The fits cover a region from threshold to 3 GeV, in the laboratory kinetic energy, for proton-proton scattering, with an upper limit of 1.3 GeV for neutron-proton scattering.
• Experiments carried out at the COSY-WASA and COSY-ANKE facilities have had a significant impact on the partial-wave solutions.
• Results are discussed in terms of both partial-wave and direct reconstruction amplitudes.
