Research

The group research interests cover a wide range from studies of QCD production to the standard model Higgs boson searches. The present research activities exploit the data produced by the Large Hadron Collider (LHC) at CERN during its run at 7 TeV and at 8 TeV, and collected by the Compact Muon Solenoid (CMS) detector. From the very beginning of the LHC run, the group has been involved in heavy flavour related analysis, concentrating on highly efficient and pure detection of beauty quarks (bottom quarks).

Our group was part of the overall CMS collaboration effort that discovered a new Higgs boson as announced on July 4th, 2012 at CERN. The characteristics  of this boson and the detailed study of its properties are the present goals of the group. We are invloved now in Run 2 (at 13 TeV) concentrating on H-->bb decays. (see CMS-homepage)

At the Paul-Scherrer-Institut (PSI) we are involved in the Mu3e experiment to search for the lepton-flavour violating decay where an anti-muon decays into two positrons and an electron without accompanying neutrinos. Any observation of this decay mode is a clean indication of physics beyond the realm of our standard model.

Quantum-aided frequency measurements

Accurate measurements of the frequencies of weak electric or magnetic fields are important in many applications. Researchers at ETH Zurich have now developed a procedure whereby a quantum sensor measures the frequency of an oscillating magnetic field with unprecedented accuracy. Read more

One laser is enough

Gases in the environment can be spectroscopically probed fast and precisely using so-called dual frequency combs. Researchers at ETH have now developed a method by which such frequency combs can be created much more simply and cheaply than before. Read more

Pauli Lectures take a look under the microscope

Using a trick with the optical resolution limit, Stefan W. Hell managed to break through the diffraction barrier in light microscopy, making it possible to obtain high-resolution images of the innermost workings of life. The chemistry Nobel laureate will now deliver this year’s Pauli Lectures at ETH Zurich. Read more
