Search for new bottomlike quark pair decays QQ¯?(tW) (t¯W^±) in same-charge dilepton events

Abstract: 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, ?), several hadronic jets, and missing transverse energy. An analysis of data from p¯p collisions with an integrated luminosity of 2.7??fb?1 collected with the CDF II detector at Fermilab yields no evidence for such a signal, setting mass limits mb?, mB>338??GeV/c2 and mT5/3>365??GeV/c2 at 95% confidence level.
