Abstract:

A search is presented for production of a heavy up-type quark (t') together with its antiparticle, assuming subsequent decay to a W boson and a b quark, t't ̄ '→W + bW - b̄. The search is based on 1.04fb - 1 of proton-proton collisions at √s=7TeV collected by the ATLAS detector at the CERN Large Hadron Collider. Data are analyzed in the lepton+jets final state, characterized by a high transverse momentum isolated electron or muon, high missing transverse momentum, and at least three jets. No significant excess of events above the background expectation is observed. A 95% C.L. lower limit of 404GeV is set for the mass of the t' quark. © 2012 CERN.
