Abstract
In this report the deuteron-proton elastic scattering reaction is studied in the range of the deuteron kinetic energy from 500 MeV to 1300 MeV. dp-elastic scattering is considered in the relativistic multiple scattering expansion framework since the Faddeev calculation technique is not applicable at these energies. We start from the AGS-equations and iterate them up to a second-order of the nucleon-nucleon interaction. The four contributions are included into consideration: one-nucleon exchange (ONE), single scattering, double scattering, and the term corresponding the delta excitation in the intermediate state. The calculations are performed for four deuteron energies: 500, 880, 1200, and 1300 MeV. The results are presented in comparison with the experimental data on the dp-elastic scattering cross section.
Highlights
Elastic deuteron-proton scattering is the simplest example of the hadron nucleus collision, because a deuteron is the simplest nucleus containing only one proton and one neutron
We got a reasonable agreement for the differential cross sections between the theoretical predictions and the experimental data almost in a whole angular range
Later the double-scattering diagram with Δ-isobar in the intermediate state was taken into account in dp backward scattering
Summary
Elastic deuteron-proton scattering is the simplest example of the hadron nucleus collision, because a deuteron is the simplest nucleus containing only one proton and one neutron. One-nucleon-exchange (ONE), single-scattering (SS), and double scattering (DS), were taken into account. The rise of the differential cross sections at the scattering angle larger than 140◦ was not described in the approach [1],[2].
