“…Fig.3, we can see that all of the calculations including nonrelativistic CD-Bonn give a quite good description of the 1 P + 1 state. In our previous works [35,36], it was shown that the one-rank kernel is already sufficient to reproduce the phase shifts in this case. The reason is the simplicity of their behavior and the narrowness of the energy interval where they are known.…”

“…Therefore, we introduce functions g p,Q of type without poles on the real axis in the relative energy p 0 complex plane. As an example of a function like that we introduce the covariant form factors in the following form (see also section 3 of [35]):…”

“…So for this special case the three-rank interaction kernel was elaborated. Its form factors have the following form: 1,2 is introduced to compensate an additional dimension in the denominator to provide the total dimension as GeV −2 [35].…”

“…The parametrization like that was proposed in [34]. In our previous works [35,36], we constructed the one-rank interaction kernel of the same type. Due to the simplicity it works till the laboratory energy T Lab ∼1 GeV except the simplest partial wave 1 P + 1 where it gives satisfactory results for all available experimental data.…”

The multirank separable kernels of the neutron-proton interaction for uncoupled S and P partial waves (with the total angular momentum J=0,1) are proposed. Two different methods of a relativistic generalization of initially nonrelativistic form factors parametrizing the kernel are considered. Using the constructed kernels the experimental data for phase shifts in the elastic neutron-proton scattering for the laboratory energy up to 3 GeV and lowenergy parameters are described. The comparison of our results with other model calculations are presented.

Covariant separable interaction for the neutron–proton system in – partial-wave state

et al. 2010

Within a covariant Bethe-Salpeter approach a rank-six separable neutron-proton interaction kernel for the triplet coupled 3 S 1 -3 D 1 partial-wave state is constructed. Two different methods of a relativistic generalization of initially nonrelativistic form factors parametrizing the kernel are considered. The model parameters are determined by fitting the elastic 3 S 1 and 3 D 1 phase shifts and the triplet scattering length as well as the asymptotic D/S ratio of the deuteron wave functions and the deuteron binding energy. The D-state probability constraints 4-7% are taken into account. The deuteron magnetic moment is calculated. The half-off-shell properties are further demonstrated by the Noyes-Kowalski functions. The first test of the constructed kernel is performed by calculating the deuteron electrodisintegration at three different kinematic conditions.
