Abstract

We have made a new measurement of the electron’s electric dipole moment (EDM) using a beam of YbF molecules.    By measuring atto-eV energy shifts in a molecule, this experiment probes new physics at the tera-eV energy scale. According to the standard model, this EDM is d_e=10^(-38) e.cm – some eleven orders of magnitude below the current experimental limit. However, most extensions to the standard model predict much larger values, potentially accessible to measurement .  Hence, the search for the electron EDM is a search for physics beyond the standard model. I will describe our experimental method, our current results and their implications for particle physics.  I will also outline the prospects for further major improvement in sensitivity.
