Abstract:

Electric dipole moment (EDM) experiments search for sources of CP violation not contained in the Standard Model (SM). Because the EDMs, predicted by the SM, are too small to be observed, the mere observation of an EDM is proof of new CP violation. Many SM extensions predict measurable or nearly measurable EDMs. Split SUSY predicts an electron EDM just below to the present experimental limit. The first electron EDM experiment using cold atoms has been demonstrated at LBNL http://arxiv.org/abs/physics/0602011 and will be described. A full-scale experiment should be capable of discovering, or ruling our, an electron EDM two orders of magnitude below the present limit. Plans (hopes) for doing this experiment in the building 50 complex will be discussed.
