Search for Higgs to WW (lnulnu,lnuqq)

A Higgs boson search in the hwwlnln ($ell=e,mu$) decay mode, using lumi fb$^{-1}$ of proton-proton collisions at a centre-of-mass energy of 7 TeV collected with the ATLAS detector, is presented. An upper bound is placed on the Higgs boson production cross-section as a function of $m_H$. 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 $142 leq m_H leq 186$~GeV. An excess of events in data corresponding to more than $2sigma$ significance is observed for the Higgs boson mass range from 126~GeV to 158~GeV.
