Abstract: A search is presented for heavy-quark pair production (QQ⁻) under the decay hypothesis QQ⁻→W⁺qW⁻q⁻ with q = d, s, b for up-type Q or q = u, c for down-type Q. The search is performed with 1.04  fb⁻¹ of integrated luminosity from pp collisions at √s = 7  TeV collected by the ATLAS detector at the CERN LHC. Dilepton final states are selected, requiring large missing transverse momentum and at least two jets. Mass reconstruction of heavy-quark candidates is performed by assuming that the W boson decay products are nearly collinear. The data are in agreement with standard model expectations; a heavy quark with mass less than 350 GeV is excluded at 95% confidence level.
