Our groups contribute to fundamental particle physics research at the Compact Muon Solenoid (CMS) experiment at the (CERN)'s Large Hadron Collider (LHC), the highest energy collider in the world. CMS measures properties of the standard model of particle interactions as well as differences from the standard model that could mean discoveries of new forces and particles. Our University of Zurich group performs in-depth investigations of the Higgs boson's properties and its relationship with the top quark, the most massive particle known to exist. We search for evidence for dark matter candidates with the CMS data. We search for signatures of extra spatial dimensions of the universe and new strong interactions that could mean some of our fundamental particles are really composite objects. Our groups are a major contributor of the CMS inner tracking detector (silicon pixel detector), which can take 65 MPixel photos of LHC collisions every 25 nanoseconds, in order to precisely identify the dominant decay mode of the Higgs boson to b quarks with micrometer precision. We have helped build the currently operating detector, and we are calibrating and maintaining this system as we build an improved version with more tracking layers, less material, and higher data rates to be installed in 2017. We are now starting to design the next generation, future inner tracker to be installed in 2023.
