Analysis of main decay channels and backgrounds
Simulation results for 7, 10, and 14 TeV energies
Abstract
ATLAS exclusion and discovery potentials of Standard Model Higgs boson searches at the LHC at 14 TeV, 10 TeV and 7 TeV center-of-mass energy are reviewed. For a LHC center-of-mass energy of 7 TeV and integrated luminosity of 1 fb, contributions from the important decay channels , and are considered, based on recent full Monte Carlo simulations at 14 and 10 TeV and the cross-section rescaling for the 7 TeV center-of-mass energy. First measurements of backgrounds to Standard Model Higgs boson search are also presented.
