The Standard Model predicts an eEDM less than $10^{-38}$e.cm, however many popular extensions predict values in the range $10^{-29}-10^{-24}$e.cm. Our experiment currently has the potential to measure eEDMs down to approximately $10^{-29}$e.cm, making it a precise probe for T-violation and physics beyond the Standard Model. We measure the eEDM by performing a type of separated oscillating field interferometry on a pulsed beam of YbF. The molecules are prepared such that the molecular spin is oriented perpendicular to an applied strong (10kV/cm) electric field. The spin is then allowed to precess about the electric field axis over a 0.5ms interaction period. We measure this angle of rotation, which is directly proportional to the eEDM. In order to measure the eEDM precisely and without error we use a complex switching technique wherein certain parameters, including the applied electric and magnetic fields, are reversed between individual molecular pulses. I will present our current technique and our most recent world leading result. en_US dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title MEASURING THE ELECTRON ELECTRIC DIPOLE MOMENT USING YTTERBIUM FLUORIDE MOLECULES en_US dc.type Article en_US dc.type Image en_US dc.type Presentation en_US
