Search for the Standard Model Higgs boson in the H →WW(?) decay mode with 4.7 fb~(-1) of ATLAS data at √s = 7 TeV

摘要

A Higgs boson search in the H →WW(?) decay mode has been performed using 4.7 fb~(-1) of proton-proton collisions at a centre-of-mass energy of 7 TeV collected in 2011 with the ATLAS detector. The search in the final state with two leptons and two neutrinos covers a broad Higgs boson mass range from 110 to 600 GeV. In addition, the high mass region from 300 to 600 GeV is explored by the semi-leptonic final state with a lepton, neutrino and two or more jets. Upper limits are derived on the cross section of a Standard Model Higgs boson.
