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 involved now in Run 2 (at 13 TeV) concentrating on H-->bb decays.

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.
