Professor Baeßler does research in fundamental physics with neutrons and related topics. 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 in hadronic weak interactions (npdgamma). In addition, he is testing gravity with ultracold neutrons at the ILL in Grenoble/France (GRANIT).
