Search for the Higgs boson in the H->WW->lnln decay mode with the ATLAS Detector
A Higgs boson search in the \hwwlnln\ ($\ell=e,\mu$) decay mode has been performed using \lumi\ fb$^{-1}$ of proton-proton collisions at a centre-of-mass energy of 7 TeV collected with the ATLAS detector. No signficant evidence of a Standard Model Higgs boson is found. An upper bound is placed on th...

| description | A Higgs boson search in the \hwwlnln\ ($\ell=e,\mu$) decay mode has been performed using \lumi\ fb$^{-1}$ of proton-proton collisions at a centre-of-mass energy of 7 TeV collected with the ATLAS detector. No signficant evidence of a Standard Model Higgs boson is found. An upper bound is placed on the Higgs boson production cross-section as a function of \mH. A Higgs boson with a mass in the range from 158 GeV to 186 GeV is excluded at 95\% confidence level, while the expected Higgs boson mass exclusion range is $142 \leq \mH \leq 186$~GeV. An excess of events in data corresponding to more than $2\sigma$ significance is observed for the Higgs boson mass range from 126~GeV to 158~GeV, with the largest deviation being $2.7\sigma$ for a Higgs boson mass of 130~GeV. |
