Progress towards the first direct measurement of deuteron EDM at COSY-Jülich storage ring.


Search for electric dipole moment (EDM) of particles is an important direction in the development beyond the Standard Model. Finding or limiting an EDM would provide a critical  test on any corresponding model, e.g., SUSY.

For technical reasons, the major progress in EDM searches up to now has been achieved for neutral systems (neutrons, atom, molecules). Storage rings provide a possibility of a direct search for charged particles EDM, with the potential to reach sensitivity beyond 10^-29 cm. The Cooler Synchrotron COSY at Forschungszentrum Jülich, providing beams of polarized protons and deuterons, suites well to testing and developing of the technologies necessary for such a measurement.

In this talk the technical challenges occurring in this high precision experiment are discussed and recent developments achieved by JEDI collaboration at COSY are presented.
