electron-EDM

We aim to improve the measurement of the permanent electric dipole moment of the electron (eEDM) using cold molecules. The fantastic precision with which the eEDM can be measured makes it a uniquely sensitive low-energy probe of physics beyond the Standard Model (SM) of particle physics. Our small-scale experiment performed with atomic physics techniques aims for a sensitivity of 5×10-30 e∙cm within the duration of the program (2017-2022), and thereby has the potential to make a major contribution to answering outstanding questions in both particle physics and cosmology.
