Separable kernel of nucleon-nucleon interaction in the Bethe-Salpeter approach for J = 0, 1 Original Research Article

The solution for the nucleon-nucleon (NN)T matrix in the framework of the covariant Bethe-Salpeter approach for a two spin-one-half particle system with a separable kernel of interaction is analyzed. The explicit analytical connection between parameters of the separable kernel and low energy scattering parameters, deuteron binding energy and phase shifts is established. Covariant separable kernels for positive-energy partial channels with total angular momentum View the MathML source and View the MathML source are constructed by using obtained relations.
