@article{Fleig2018ModelindependentDO, title={Model-independent determinations of the electron EDM and the role of diamagnetic atoms}, author={Timo Fleig and Martin Jung}, journal={Journal of High Energy Physics}, year={2018}, volume={2018}, pages={1-18} }

A bstractWe perform model-independent analyses extracting limits for the electric dipole moment of the electron and the P,T-odd scalar-pseudoscalar (S-PS) nucleon-electron coupling from the most recent measurements with atoms and molecules. The analysis using paramagnetic systems, only, is improved substantially by the inclusion of the recent measurement on HfF+ ions, but complicated by the fact that the corresponding constraints are largely aligned, owing to a general relation between the…
