Deuteron-proton elastic scattering at intermediate energies

Investigation of reactions using polarized and unpolarized deuteron beam at Nuclotron: current status and perspectives

“…The angular dependence of the differential cross section obtained at 940 MeV [24] and 850 MeV [25] are represented by the open circles and triangles, respectively. The solid, dashed and dot-dashed lines are the results of the non-relativistic Faddeev calculations [26], relativistic multiple scattering model [27,28] and optical potential approach [29].…”

“…The Faddeev calculations without invoking 3N forces reproduce the behaviour of the analyzing powers, however, they fail to describe the cross section data at the scattering angles larger than 70 • in the centre of mass system. The calculations performed within relativistic multiple scattering model [27,28] describes the data on the vector analyzing power A y and cross section. However, there are some problems in the description of the tensor analyzing powers at large angles in the centre of mass system.…”

“…Since present 3N forces models cannot improve the agreement with the data obtained even at lower energies, new models of 3N forces (including their short-range part) should be considered. For instance, the next step in the relativistic multiple scattering model [27,28] development could be taking into account the explicit Δ-isobar excitation. Dp elastic data have been obtained in the energy range from 0.3 to 2.0 GeV.…”

Short-range correlations studies in collisions of polarized nuclei at Nuclotron-M

“…1 by the solid symbols. The solid, dashed and dash-dotted lines are the results of the Faddeev calculations [29] using CD-Bonn nucleon-nucleon potential [30], of the relativistic multiple scattering calculations [31] using CD-Bonn [30] deuteron wave function (DWF), and the optical potential calculation [32] with the dibaryon DWF [15], respectively. One can see that Faddeev and relativistic multiple scattering models give good description of the data except for A xx .…”

“…One of the reasons of some discrepancy in this region can be 3N SRCs, which are not included in the calculations. These SRCs can be responsible for the deviation between the calculations [31] and data on the analyzing powers [24,25] also.…”
