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′b̅ ′→W[superscript -]tW[superscript +]t̅ →bb̅ W[superscript +]W[superscript -]W[superscript +]W[superscript -]→l[superscript ±]νbb̅ qq̅ qq̅ qq̅ . 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 1.04  fb[superscript -1] from pp collisions at √s=7   TeV recorded with the ATLAS detector, a heavy down-type quark with mass less than 480 GeV can be excluded at the 95% confidence level.
