Search for new bottomlike quark pair decays QQ̄→(tW) (t̄W±) in same-charge dilepton events

We report the most restrictive direct limits on masses of fourth-generation down-type quarks b′, and quarklike composite fermions (B or T5/3), decaying promptly to tW. We search for a significant excess of events with two same-charge leptons (e, μ), several hadronic jets, and missing transverse ener...
