AB  - The JEDI (Jülich Electric Dipole moment Investigations) collaboration performs a set of exper-iments at the COSY storage ring of the Forschungszentrum Jülich in Germany, within the R&Dphase to search for the Electric Dipole Moments (EDMs) of charged particles. A measurement ofproton and deuteron EDMs is a sensitive probe of yet unknown CP violation. An EDM observa-tion would also be an indication for physics beyond the Standard Model.The method of charged particle EDM search will exploit stored polarized beams in order to ob-serve a miniscule rotation of the polarization axis as a function of time due to the interaction ofa finite EDM with large electric fields. Key challenge is the provision of a sensitive and efficientmethod to determine the tiny change of the beam polarization. Elastic scattering of the beamparticles on carbon nuclei will provide the polarimetry reaction. For this reason and as an inputfor future Monte-Carlo simulations, a good knowledge of the vector analyzing power and the un-polarized elastic cross section of deuterons scattered off a carbon target is very important to beable to determine the deuteron polarization. Over the course our experiment, the analyzing powerand the differential cross section was measured using six different beam energies starting from 170 MeV up to 380 MeV deuterons.
