Search for pair production of a heavy up-type quark decaying to a W boson and a b quark in the lepton+jets channel with the ATLAS detector

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...
