Search for the Associated Higgs Boson Production in the WHâ WWW(â)â lνlνlν Decay Mode Using 4.7 fbâ1of Data Collected with the ATLAS Detector at âs = 7 TeV
A search for the Higgs boson in the associated production mode WHâ WWW(â)â lνlνlν (l = e, μ) has been performed using 4.7 fbâ1 of proton-proton collision data at a centre-of-mass energy of 7 TeV collected in 2011 with the ATLAS detector. No excess above background is observed. Within the mass range 110 GeV ⤠mH ⤠300 GeV 95% CL limits are set from 2.7 to 43 times the Standard Model prediction, with the best limit being set at mH=165 GeV.
