Abstract
Measurement of the electric dipole moment of a fundamental
particle is one way in which to search for physics beyond the Standard
Model. In this talk I will review current experiments which set limits on
the electric dipole moment of the electron. All these experiments use heavy
polar molecules. I will concentrate in particular on the experiment at
Imperial College which uses YbF. I will also explain how new techniques of
directly laser cooling of molecules have increased the sensitivity of this
experiment, and how in these techniques will lead to an ever larger
sensitivity increase in the near future.
