A permanent electric dipole moment (EDM) implies breakdown of P (parity) and T (time reversal) symmetries. Provided CPT holds, this implies CP violation. Observation of an EDM at achievable experimental sensitivity would provide unambiguous evidence for physics beyond the Standard Model and limits towards matter-antimatter asymmetry. Our experiment uses differential spin precession of 3He and 129Xe, co-occupying the same volume, to measure the EDM of xenon. We have reached in a first test already sensitivity in the range 10-28 ecm. I will present the current status of the experiment and challenges like long term (weeks) tight control over magnetic and electric fields.
