Stefan Baeßler

Professor Baeßler does research in fundamental symmetries, that is, precision tests of the Standard Model of Elementary Particles. His main activities are devoted to physics with cold neutrons at the SNS in Oak Ridge/Tennessee. He conducts experiments that study neutron beta decay (Nab and pNab). In addition, he is testing gravity with cold and ultracold neutrons at the ILL in Grenoble/France (GRANIT), and he is determining the magnetic moment of the muon (g-2) at Fermilab and tries to explain why it deviates from theory (MUonE) at CERN.
