Abstract

A search for a Higgs boson has been performed in the H → WW → ℓνjj channel in 1.04  fb^(-1) of pp collision data at √s=7  TeV recorded with the ATLAS detector at the Large Hadron Collider. No significant excess of events is observed over the expected background and limits on the Higgs boson production cross section are derived for a Higgs boson mass in the range 240  GeV < m_H < 600  GeV. The best sensitivity is reached for m_H = 400  GeV, where the 95% confidence level upper bound on the cross section for H → WW production is 3.1 pb, or 2.7 times the standard model prediction.
