Abstract
Energy dependence of the vector $A_y$ and tensor $A_{yy}$ and $A_{xx}$ analyzing powers in deuteron-proton (dp) elastic scattering is investigated in the energy range from 400 - 2000 MeV at large scattering angles. The detection of the dp elastic scattering events has been done by the coincident measurement of deuteron and proton in the the angular range of 60$^{\circ}$-135$^{\circ}$ in the cm. Preliminary results of differential cross sections and analyzing powers for dp elastic scattering are compared with theoretical predictions based on relativistic multi-scattering model which includes besides single and double scattering terms also delta isobar excitation. There are interesting parts of deuteron proton breakup reaction phase space in which three nucleon forces, relativistic or coulomb effects can be studied separately. Preliminary results of the cross section of the dp breakup reaction have been obtained in the energy range from 300 - 500 MeV of incoming deuteron for particular detector configurations in which the sensitivity to the nucleon-nucleon, three nucleon forces as well as relativistic effects are assumed. All measurements were performed at Nuclotron (JINR, Dubna).
