Projected Sensitivity of the JILA Gen. II eEDM Experiment

ORAL

Abstract

A new limit on the permanent electric dipole moment of the electron (eEDM) will probe physics beyond the standard model and shed light on open questions such as the baryon asymmetry and dark matter.  Our upcoming measurement of the eEDM uses a thermal cloud of HfF+ ions held in an RF trap, allowing us to leverage second-scale coherence times and the large internal electric fields present in polar molecules.  This talk will detail the second generation experimental setup, and our analysis of roughly 40 hours of near quantum projection noise limited precision data to project the final sensitivity of our measurement.  We expect to reach a statistical sensitivity of 30 μHz with 200 hours of data, and together with systematic evaluations, could potentially set a new limit on the eEDM with an uncertainty of less than 10-29 e cm at the 90% confidence interval.
