Abstract

Preliminary results on the angular distributions of the vector Ay and tensor Ayy, Axx analyzing powers in dp elastic scattering at the energy of 800 MeV are presented. The measurements have been performed on Internal Target Station of the JINR Nuclotron using polarized deuteron beam from new source of polarized ions. The experimental data are compared with the preliminary calculations obtained within framework of relativistic multiple scattering approach.

Highlights

The main activity in the spin studies at the Laboratory of High Energy Physics of the Joint Institute for Nuclear Research (LHEP-JINR) at the Nuclotron is related to the short range correlations (SRCs) in nuclei

Summary

Introduction

The main activity in the spin studies at the Laboratory of High Energy Physics of the Joint Institute for Nuclear Research (LHEP-JINR) at the Nuclotron is related to the short range correlations (SRCs) in nuclei. The physics of SRCs deals with the understanding of the role of the QCD in the formation of nuclear forces at short distances and with the understanding of the dynamics of the super-dense cold nuclear matter. Despite the fact that spin physics is being studied rather actively still many open problems exist both in experimental and theoretical aspects. At energies below the π production threshold (E = 210 MeV /nucleon), these potentials provide rigorous description of the experimental data. These NN forces fail to recreate experimental binding energies of few-nucleon systems.
