Abstract

The deuteron–proton elastic scattering process is considered in the relativistic expansion framework. Four reaction mechanisms are taken into account: plane-wave impulse approximation, single-scattering, double-scattering terms, and delta-isobar in the intermediate state. Each of these terms contributes into the reaction amplitude. The method allows calculating both the differential cross section and any polarization observables. The calculations are performed in a GeV-energy range for the special case when the scattering angle is equal to 180 degrees. The results are given for various deuteron wave functions: Paris, CD Bonn, and Gross.
