|
The single particle response of the ATLAS Inner Detector has been simulated. The impact parameter resolution was parameterised as sigma (d0) = 11 ⊕ 59/pT mum and sigma(z0) = 85 ⊕ 94/pT mum with pT in GeV. The b-tagging performance was evaluated, for a b-tagging efficency eb = 0.5, the light quark rejection Ru = 83 +/- 6 for 97% silicon microstrip and pixel detector efficiency and Ru = 61 +/- 4 for 90% detector efficiency for 200 GeV jets. The viability for a Higgs boson search using the channel ttH → bW+bW-bb was examined. For a total integrated luminosity of 3 . 10e4pb-1 and a Higgs boson of mass mH = 80 GeV the signal significance was 11.7, for MH = 100 GeV 6.5, above mH = 110 GeV the signal significance fell below the 5sigma level.
