Abstract
The results of the differential cross section of elastic dp-scattering measurements at 500, 750 and 900 MeV/n, performed at the Internal Target Station at the JINR Nuclotron are presented. The angular dependence is compared with the world experimental data at close energies as well as with the theoretical calculations performed within the framework of the relativistic multiple scattering theory. The differential cross section at fixed scattering angles covered a total c.m. energy range $\rad{}{s} = 3.1 - 3.42\,{\rm{GeV}}$ were obtained. The results are compared with the behavior of the world data.
Highlights
The d p-elastic scattering process is the simplest example of the hadron nucleus collision
The approaches based on the solution of the three-particle Schroedinger equation [11,12,13] and on the Faddeev calculations [14, 15] are described of the three-nucleon scattering with high accuracy at the energies below 200 MeV/n [16, 17]
At high energies and large transverse momenta the constituent counting rules (CCR) [30] predict the 1/sn−2 dependence of the differential cross section for the binary reaction, where n is the total number of the fundamental constituents involved in the reaction
Summary
The d p-elastic scattering process is the simplest example of the hadron nucleus collision. The approach based on the multiple-scattering theory which uses off-mass-shell extrapolations of the nucleon-nucleon amplitudes is developed [20, 21]. These calculations were applied to describe the d p-elastic scattering differential cross section at the energies up to 1000 MeV/n [21,22,23,24]. In this paper the angular dependences of the differential cross section for dp-elastic scattering at 500, 750 and 900 MeV/n, obtained at Internal Target Station (ITS) at the Nuclotron are presented
