摘要: A search for the Standard Model Higgs boson at Large Hadron Collider (LHC) running a centre-of-mass energy of 7 TeV is reported, based on total integrated luminosity up to 40 pb-1 collected by ATLAS detector in 2010. Several decay channels: H \rightarrow {\gamma}{\gamma}, ZZ (*) llll, ll{\nu}{\nu}, llqq, W l{\nu}l{\nu} and l{\nu}qq (l e, {\mu}) are combined mass range from 110 GeV 600 GeV. The highest sensitivity achieved between 160 170 GeV, where expected 95% CL exclusion production cross sections 2.3 times prediction. Upper limits section its determined. Models with fourth generation heavy leptons quarks Model-like couplings also investigated excluded 140 185
