We study deuteron- proton elastic scattering in the deuteron energy
range between 500 MeV and 2 GeV at the cms scattering angle
\theta^*\ge 140^\circθ*≥140∘.
The reaction is considered in the relativistic multiple scattering
expansion framework. The four reaction mechanisms are included into
consideration: one-nucleon exchange, single scattering, double
scattering, and the term corresponding to the delta excitation in the
intermediate state.The model is applied to describe the angular dependence of the
differential cross section at the deuteron energies of between 880 and
1300 MeV. Also the energy dependence of the differential cross section
and polarisation observables such as tensor analyzing power
T_{20}T20
and polarization transfer from the deuteron to proton
\varkappa𝜘
are considered at the scattering angle equal to
180^\circ∘.
Contributions of the different reaction mechanisms into the reaction
amplitude are demonstrated in comparison with the existing experimental
data.
