Abstract
The most accepted approach to describe nucleon-nucleon (NN) interaction is the partial wave analysis (PWA), which translates various experimental observables to the common language of the partial waves. The reliable analysis relies not only on the quality experimental data, but also on the measurements of scattering observables over preferably the full angular range. Small angle scattering has been measured for six beam energies between 0.8 and 2.4 GeV using polarized proton beam incident on both proton and deuteron unpolarized targets at COSY-ANKE. This proceeding will report on the published and preliminary results for both pp and pn scattering from this and other recent experiments at ANKE. This study aims to provide the valuable observables to the SAID group in order to improve the phenomenological understanding of the nucleon-nucleon interaction.
Highlights
The interactions between nucleons and their constituent quarks and gluons, are mainly governed by the strong interaction
The SAID data base and analysis (Scattering Analysis Interactive Dialin) [1] have proved to be a truly invaluable tool over many years for researchers working in this area
The COoler SYnchrotron (COSY)-ANKE facility was designed for the investigation of the small angle region and is well suited to cover this significant gap in the database
Summary
The interactions between nucleons and their constituent quarks and gluons, are mainly governed by the strong interaction. The only feasible approach to describe nucleon interaction at intermediate energies is phenomenological one. The SAID data base and analysis (Scattering Analysis Interactive Dialin) [1] have proved to be a truly invaluable tool over many years for researchers working in this area. Such an analysis is based on the measurements of various NN scattering observables at different energies over the full angular range.
