The CMS analysis group at HEPHY uses data from proton-proton collisions that are produced in CERN's Large Hadron Collider (LHC) at the highest energies that can currently be achieved. The particles generated in these collisions are recorded by the CMS experiment and allow the extension of our knowledge of elementary particles and the forces acting between them.
One of the priorities of research at the LHC is the search for new particles and processes, which are not predicted by the current "standard model" of particle physics. The discovery of a Higgs boson at the LHC has completed this model and essentially validated its predictions. However, it has several shortcomings, with the lack of an explanation for "dark matter" as one of the most prominent ones.
The CMS analysis group at HEPHY has a leading role in the search for evidence for extensions of the standard model. Different approaches are used: the direct search for new particles that could be generated in the collisions, and the indirect search using precision measurements and comparison with the predictions of the standard model.
The activities of the analysis group are focused on the following areas:
