Systematic and statistical uncertainty evaluation of the HfF+ electron electric dipole moment experiment
Abstract
We have completed a new precision measurement of the electron's electric dipole moment using trapped HfF+ in rotating bias fields. We report on the accuracy evaluation of this measurement, describing the mechanisms behind our systematic shifts. Our systematic uncertainty is reduced by a factor of 30 compared to the first generation of this measurement. Our combined statistical and systematic accuracy is improved by a factor of 2 relative to any previous measurement.
