NL-eEDM

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 has the potential to make a major contribution to answering outstanding questions in both particle physics and cosmology.

Ameland Summerschool 2025

Early this summer we have enjoyed a very nice fourth edition of our bi-annual summerschool 'Searches for new physics with low-energy precision tests', on the Dutch island of Ameland. We had a week with exciting lectures, short student presentations, fu...
