Description

A non-zero permanent electric dipole moment (EDM) of an electron would violate parity and time- reversal symmetries. Non-zero EDMs are predicted in the Standard Model, but are unobservably small. New physics incorporating new particles and new CP-violating phases can lead, through radiative cor- rections, to dramatic enhancements of the electron EDM, to within a few orders of magnitude of the current experimental limit, jdej < 1:0£10¡27 e cm. A possible new approach to electron EDM searches using molec- ular ions stored in a table-top electrostatic storage ring is described. Molecular ions with long-lived paramagnetic states such as WN+ could be injected and stored in large numbers and with long coherence times. Sensitivities approaching a few £10¡30 e cm/ p day, appear possible, a potential improvement by three orders of magnitude. D
