Particle Physics

We study the constituents of matter and their fundamental interactions using data of the Compact Muon Solenoid (CMS) experiment. Our studies range from the study of the top quark and the Higgs boson to the search for new phenomena beyond the standard model. Our group also contributes to technical areas like the calibration of the jets and missing transverse momentum, support of the german NAF and the development and maintenance of the reconstruction and analysis software. In addition, we are involved in the Gfitter project. (image source: CMS/CERN)

Detector Development

A strong focus of our group is the development of silicon detectors, in particular for the CMS experiment. In a dedicated silicon lab we develop radiation hard silicon materials able to withstand the high particle fluxes at LHC and SLHC and participate in the RD50 collaboration. Sensor design was done for the ZEUS micro vertex detector and is currently studied for the upgrade of the CMS pixel detector. Large scale detector production was done for both ZEUS and CMS.
Our group is also strongly involved in characterization of Silicon-PhotoMultipliers (SiPM) and their applications to high-energy physics and medical fields. We are involved in the detector development for the future linear collider, via the CALICE collaboration, aiming to develop novel calorimeter designs for the application of particle flow techniques. As a spin-off of this activity the group is also active in the medical exploitation of SiPM to Time of Flight Positron Emission Tomography.
