On the covariant relativistic separable kernel

Nuclear Theory 2009-01-07 v1

Abstract

Two different methods of the covariant relativistic separable kernel construction in the Bethe-Salpeter approach are considered. One of them leads in the center-of-mass system of two particles to the quasipotential equation. The constructed 4-dimensional covariant functions are used to reproduce neutron-proton phase shifts for total angular momenta J=0,1J=0,1. Obtained results are compared with other model calculations.
