Description
We present a search for pair production of heavy quarks Q4 decaying via Q4 -> qW -> q l nu. We perform approximate mass reconstruction by assuming that the boosted W decays to a charged lepton and neutrino which are nearly collinear. We use 37 inverse picobarns of integrated luminosity from pp collisions at sqrt(s) = 7 TeV collected by the ATLAS detector. The data are in agreement with standard model expectations; we exclude at 95% confidence level a heavy quark with mass less than 270 GeV.
