TL;DR
This paper introduces a new separable kernel for the nucleon-nucleon interaction within the Bethe-Salpeter framework, fitting phase shifts to recent experimental data for neutron-proton scattering at medium and high energies.
Contribution
It presents a novel version of the separable kernel that accurately models nucleon-nucleon interactions and fits experimental phase shift data.
Findings
Phase shifts fitted to recent experimental data
Comparison with other models shows good agreement
Effective for medium and high energy nucleon interactions
Abstract
A new version of the separable kernel of the nucleon-nucleon interaction in the Bethe-Salpeter approach is presented. The phase shifts are fitted to recent experimental data for singlet and uncoupled triplet partial waves of the neutron-proton scattering with total angular momenta J=0,1. The results are compared with other model calculations.
