Experimental particle physics at the energy frontier

In 2009 the experiments at the new Large Hadron Collider (LHC) accelerator facility at CERN (Geneva) became operational. In this accelerator protons are accelerated to energies up to 7 TeV. In collisions of protons with this energy new phenomena are expected: new particles such as the Higgs-boson or supersymmetry particles. In this project we carry out precision measurements on the top quark and a search for signals of supersymmetry.
