Title: Evidence for the Higgs boson and Measurements of the properties in the WW(∗)->'ℓνℓν decay channel with the ATLAS detector
Evidence for the Higgs boson in the H -> WW -> l nu l nu channel is presented using the complete 2012 and 2011 data samples collected with the ATLAS detector at the LHC. The analysis focuses on a mass of mH = 125 GeV, where an excess over the expected number of background events is observed. A preliminary result on the properties is presented going through the details of object selection and background estimation.
