Combined search for the Standard Model Higgs boson in pp collisions
نویسنده
چکیده
A combined search for the Standard Model Higgs boson with the ATLAS detector at the LHC is presented. The data sets used correspond to integrated luminosities from 4:6 fb 1 to 4:9 fb 1 of protonproton collisions collected at ffiffi s p 1⁄4 7 TeV in 2011. The Higgs boson mass ranges of 111.4 GeV to 116.6 GeV, 119.4 GeV to 122.1 GeV, and 129.2 GeV to 541 GeVare excluded at the 95% confidence level, while the range 120 GeV to 560 GeV is expected to be excluded in the absence of a signal. An excess of events is observed at Higgs boson mass hypotheses around 126 GeV with a local significance of 2.9 standard deviations ( ). The global probability for the background to produce an excess at least as significant anywhere in the entire explored Higgs boson mass range of 110–600 GeV is estimated to be 15%, corresponding to a significance of approximately 1 .

A preliminary combined search for the Standard Model Higgs boson with the ATLAS detector at the LHC is presented. The pp collisions datasets used correspond to integrated luminosities of 4.6 fb−1 to 4.9 fb−1 at √ s = 7 TeV in 2011 and 5.8 fb−1 to 5.9 fb−1 at √ s = 8 TeV in 2012. Searches for H → γγ, H → ZZ(∗), H → WW (∗), H → bb̄, and H → τ+τ− have been performed on the 2011 data, while only the...
