Description
We study deuteron- proton elastic scattering in the GeV energy range.
Nowadays, a significant amount of the experimental data at these energies
has been accumulated both with unpolarized and polarized beams. However,
a theoretical description of the data faces problems because of
well developed Faddeev calculation technique cannot be applied at these energies.
In this report we consider deuteron- proton elastic scattering in the
relativistic multiple scattering expansion framework. The following reaction mechanisms are included into consideration: one-nucleon exchange, single scattering, and double scattering. Also, the term corresponding to the delta excitation in the intermediate state is taken into account. This model
is applied for a description of the experimental data both on the differential cross section and polarization observables in a whole angular range.
The obtained theoretical predictions are compared with the existing experimental data. Effects of the different reaction mechanisms are analyzed.
