Abstract:
This Letter presents a search for pair production of heavy down-type quarks decaying via b ′ →Wt in the lepton+jets channel, as b ′ b ̄′ →W - tW + t̄→bb̄W + W - W + W - →l ± νbb̄qq̄qq̄qq̄. In addition to requiring exactly one lepton, large missing transverse momentum, and at least six jets, the invariant mass of nearby jet pairs is used to identify high transverse momentum W bosons. In data corresponding to an integrated luminosity of 1.04fb - 1 from pp collisions at √s=7TeV recorded with the ATLAS detector, a heavy down-type quark with mass less than 480GeV can be excluded at the 95% confidence level. © 2012 CERN.
