Probing the electron EDM with cold molecules

Atomic Physics 2009-11-13 v1

Abstract

We present progress towards a new measurement of the electron electric dipole moment using a cold supersonic beam of YbF molecules. Data are currently being taken with a sensitivity of 1027e.cm/day10^{-27}\textrm{e.cm}/\sqrt{\textrm{day}}. We therefore expect to make an improvement over the Tl experiment of Commins' group, which currently gives the most precise result. We discuss the systematic and statistical errors and comment on the future prospect of making a measurement at the level of 1029e.cm/day10^{-29}\textrm{e.cm}/\sqrt{\textrm{day}}.
