Is the electron round?

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.
