Higgs Boson search at the CMS experiment

The results of the search for the Standard Model (SM) Higgs Boson with the CMS detector in proton-proton collisions at the LHC at 7 TeV center-of-mass energy are reported. A large number of the Higgs Boson decay channels in the mass range from 110 GeV to 600 GeV are considered, and combined upper limits on the production cross section as a function of the Higgs Boson mass are derived. The SM Higgs is excluded at 95% confidence level in the mass range between 127.5 GeV and 600 GeV. In addition, searches for Higgs Bosons in scenarios Beyond the Standard Model (BSM) lead to improved constraints on the Higgs sector of BSM theories such as supersymmetry.
