Search for polarization in the antiproton production process — •Dominika Alfs, Dieter Grzonka, and James Ritman — Institut für Kernphysik, Forschungszentrum Jülich, Germany

The goal of the P-349 experiment is to investigate a possible polarization of antiprotons produced in pA collisions in view of preparation of a polarized antiproton beam. Experimentally this is done by the measurement of the left-right asymmetry of elastic antiproton scattering on a liquid hydrogen target in the Coulomb-nuclear interference region.

Measurements were performed at the Proton Synchrotron test beam East Area (T11) at CERN. The analysis in ongoing, however, the expected statistics of reconstructed scattering events based on preliminary results is too low for a significant polarization analysis.

Therefore additional measurements are planned at CERN combined with precursor experiments with polarized proton scattering at Cooler Synchrotron (COSY) at Forschungszentrum Jülich.

In this talk the achieved results and details of the additional measurements will be presented.
