Further investigations of ATLAS Sensitivity to Higgs Boson Production in different assumed LHC scenarios

Projections for the ATLAS sensitivity to the Standard Model Higgs boson from LHC running at centre-of-mass energies of sqrts = 7 and 8 TeV are reported. These studies extend our previous results by considering the luminosities required to reach 5sigma discovery significance. The projections are larg...

description Projections for the ATLAS sensitivity to the Standard Model Higgs boson from LHC running at centre-of-mass energies of sqrts = 7 and 8 TeV are reported. These studies extend our previous results by considering the luminosities required to reach 5sigma discovery significance. The projections are largely derived using cross-sections rescaling to different centre-of-mass energies. The ATLAS experiment, with 1 fb−1 of data taken at sqrts = 7 TeV and using rather conservative assumptions, should have sensitivity such that Higgs boson masses between 129 and 460 GeV have at least a 50% chance of being excluded at 95% CL. If 10 fb−1 of data taken at sqrts = 8 TeV is available the 5sigma discovery region covers from 128 to over 500 GeV.
