Search for down-type fourth generation quarks with the ATLAS detector in events with one lepton and hadronically decaying W bosons

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 inva...
