ATLAS Higgs Searches
N. Andari · 2012
A combined search for the Standard Model Higgs boson with the ATLAS experiment at LHC using datasets corresponding to integrated luminosities from 1.0 to 2.3 fb -1 of pp collisions at √ s = 7 TeV is presented.The Higgs boson mass ranges 146 -230 GeV, 256 -282 GeV and 296 -459 GeV are excluded at 95% Confidence Level, while the range 131 -450 GeV is expected to be excluded in the absence of a signal.Searches in several decay channels are discussed:No significant excess was observed in any of these channels for the entire mass range from 110 to 600 GeV.In addition, a search for neutral Higgs bosons in the Minimal Supersymmetric extension to the Standard Model (MSSM) is presented.LHC on the March,
