Higgs Searches in CMS

In this seminar we will review the strategy and the results of Higgs searches in proton-proton collisions at 7 TeV centre-of-mass energy with the CMS detector at LHC. The search is performed in different final states to
optimize the sensitivity in a wide mass range. Thanks to the excellent performance of the LHC and of the CMS detector a lot of high quality data have been already analyzed. Results based on the first part of the 2011 run, corresponding to an integrated luminosity of
approximated 1.5 fb-1, will be presented. The search for the Standard Model Higgs as well as for Beyond the Standard Model Higgs bosons lead to exclusion limits that extend those obtained at LEP and at the Tevatron,. However, in the most theoretically favored low mass range of the Higgs boson more integrated luminosity is needed for its discovery or exclusion.
