Welcome to the Group for Precision Physics at Low Energy
We perform precision particle physics experiments at low energies, studying fundamental symmetries and interactions with neutrons and muons. Our group is involved in several experiments such as muonic hydrogen and helium, muon cooling, muonium production and neutron electron dipole moment.
In our research on muonic atoms, one of our goals is to use x-ray spectroscopy on systems with a very light nucleus (Z = 3–10) to accurately measure their nuclear charge radii. To achieve this, we employ metallic magnetic calorimeters, a promising detector technology capable of delivering world-record resolving powers for x-ray energies spanning a few keV to a few hundred keV.
Our EPT-hub concluded the year 2023 by hosting the «Afternoon of Science and Teaching» event in collaboration with the MaP Doctoral School.
Special Communication
Information on the coronavirus
The ETH task force headed by the Vice President for Infrastructure is monitoring developments in the coronavirus pandemic and will continue to draw up suitable measures as necessary. You can find constantly updated information on the coronavirus web page.
Annette Oxenius has been appointed ETH Vice President for Research. From 1 August 2025, she will assume responsibility for research development and promotion at ETH Zurich. The 56-year-old Swiss national is an esteemed immunologist and professor at the ETH Department of Biology.
During the COVID-19 pandemic, hospitals often became hubs of infection. Researchers from ETH Zurich, EPFL and the ISI Foundation are developing a wearable tracking system for healthcare facilities that can identify the risks of infections. Initial tests in Switzerland and Africa show its potential.
A new study by various Swiss universities shows that aerosols in indoor air can vary in acidity. This acidity determines how long viruses remain infectious in the air – with profound implications for virus transmission and strategies to contain it.
