Search for pair-produced heavy quarks decaying to Wq in the two-lepton channel at √(s)=7 TeV with the ATLAS detector
A search is presented for heavy-quark pair production (QQ̅) under the decay hypothesis QQ̅→W[superscript +]qW[superscript -]q̅ with q=d, s, b for up-type Q or q=u, c for down-type Q.

| Summary: | A search is presented for heavy-quark pair production (QQ̅) under the decay hypothesis QQ̅→W[superscript +]qW[superscript -]q̅ 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[superscript -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. |
