CMS Physics Analysis

With the discovery of the Higgs Boson at the Large Hadron Collider (LHC) at CERN, the "Standard Model" of particle physics is completed and its predictions essentially confirmed. CMS data are now used to scrutinize the model to even greater detail using precision measurements, and, most importantly, to search for New Physics beyond the Standard Model.


Research interests. The CMS group at HEPHY is strongly engaged in physics analysis and concentrates on two main areas.

  • The first one targets a better understanding of quantum chromodynamics (QCD) - the theory of the strong interaction, which is the central element at a hadron collider like LHC. We use the production rate and the spin orientation of quarkonia - bound states of a heavy quark with its anti-particle - to verify the predictions of QCD calculations.
  • The second area is built around the search for "New Physics" beyond the Standard Model. In particular we are looking for hints for the production of supersymmetric particles in collision events featuring a high-energetic lepton and a significant imbalance in the sum of all particle momenta measured by the detector.
