Status of Higgs boson searches in the CMS experiment at the CERN LHC

The last unconfirmed part of the standard model of particle physics is the spontaneous breaking of the electroweak symmetry, which is assumed to account for the generation of masses of different particles through the Higgs mechanism. The Higgs mechanism requires, however, the existence of one or more Higgs bosons, which so far have not been experimentally discovered. Since the mass of the Higgs boson is limited by theoretical constraints below the TeV energy scale, the LHC and its general-purpose detectors, including the CMS experiment, are expected to be in a position to either confirm or exclude the existence of the Higgs boson. The current status of efforts for finding the Higgs boson at the CMS experiment is discussed for both the standard model (SM) and the minimal supersymmetric standard model (MSSM). Results based on the 36 pb-1 of data collected in 2010 are presented [1].
