Higgs Physics with the CMS Experiment

For a long time, the Higgs boson was one of the missing pieces of the Standard Model (SM). It has been predicted in 1964 as a consequence of a mechanism which explains the masses of the known particles. In July 2012, the discovery of a Higgs-like particle has been announced by the ATLAS and CMS experiment. Since then, many of the properties of this particle have been studied by the CMS collaboration strengthening the believe that the new particle is indeed the long search Higgs boson of the SM.

Many SM extensions (like e.g. SUSY), however, predict a more complex Higgs sector featuring a rich collider phenomenology. Therefore, studying Higgs physics can also open the window to new physics. In our group, we are measuring Higgs properties and we are looking for new, non-SM, Higgs-like particles.
