Description

The main goal is to perform precision particle physics experiments at low energies, studying fundamental symmetries and interactions with neutrons and muons.

With an international collaboration, we are performing an improved measurement of the neutron electric dipole moment (nEDM) at the Paul Scherrer Institiut (PSI).

The nEDM is a most sensitive probe for new sources of CP-violation, needed in order to understand the apparent matter-antimatter asymmetry of the universe. A finite value of the nEDM would be a signal of new physics beyond the Standard Model of electro-weak interaction.

Further, our group is working on fundamental physics projects with muons. The development of new high quality beams and the study of muonic atoms, such as muonium and muonic Helium, is in the focus of our work. Fundamental theories will be tested and fundamental constants extracted. We are developing our experiments in our laboratory at the ETH Zurich and in close collaboration with groups at the PSI.
