LTP: Laboratory for Particle Physics
Scientific Highlights and News
Swiss National Science Foundation Ambizione grant for Franziska Hagelstein
Franziska Hagelstein has been awarded a Swiss National Science Foundation Ambizione grant with PSI as host institution. She joined the particle theory group (NUM, Laboratory of Particle Physics LTP) in October 2020. In the near future she will be accompanied by a PhD student.
Global Fit to Modified Neutrino Couplings and the Cabibbo-Angle Anomaly
Recently, discrepancies of up to 4σ between the different determinations of the Cabibbo angle were observed. In this context, we point out that this “Cabibbo-angle anomaly” can be explained by lepton flavor universality violating new physics in the neutrino sector. However, modified neutrino couplings to standard model gauge bosons also affect many other observables sensitive to lepton flavor universality violation, which have to be taken into account in order to assess the viability of this explanation.
Mu3e magnet arrived at PSI
After almost three years of planning, design and construction, the 31-ton, 2.6 Tesla superconducting magnet for the Mu3e experiment arrived today at PSI. The magnet delivery is an important milestone in the Mu3e experiment at the Laboratory of Particle Physics LTP, which will search for New Physics in muon decays over the next years.
In search of new physics
With the high-intensity proton accelerator HIPA, the Paul Scherrer Institute generates elementary particles to clarify how the universe is structured. Using pions, muons, and neutrons, the researchers conduct experiments to test the standard model of particle physics.
Anna Sótér appointed Tenure Track Assistant Professor at ETH Zurich
Anna Sótér, currently Lecturer and SNSF Ambizione Fellow at ETH Zurich, formerly member of the PSI Laboratory for Particle Physics and member of the PSI Fellow program, has been appointed Tenure Track Assistant Professor of Low Energy Particle Physics. Anna Sótér’s research is in the area of exotic atoms, where particle physics, atomic physics and quantum optics meet.
