Welcome to the research group of Prof. Dr. Martin Fertl

Our research group focuses on the high-precision determination of properties of neutrons, muons and neutrinos. These elementary systems provide superb test beds of the Standard Model of Particle Physics and the Standard Model of Cosmology.

The tSPECT experiment aims at a precise determination of the lifetime of the free neutron using the magnetic bottle technique with ultracold neutron.

The Muon g-2 experiment aims at measuring the anomalous magnetic moment of the muon to the unprecedented precision of 140 parts-per-billion. This will allow to test a tantalizing discrepancy between prediction given by the Standard Model of Particle Physics and the result of the latest experiment.

The Project 8 collaboration has recently demonstrated the novel technique of cyclotron radiation emission spectroscopy with single electrons which opened a new avenue in precision nuclear decay studies. Ultimately we aim to apply this new technology to a precision determination of the decay spectrum of atomic tritium to reach a sensitivity to the effective electron neutrino mass beyond the reach of the current state of the art technology.
