Abstract

The production of fourth-generation quarks at the Superconducting Super Collider is studied concentrating on event signatures resulting from the single-lepton and two-lepton decay modes. We find that events with multijets (njet≥3) and one or two high-pT leptons are good signals for heavy-quark production for quark masses up to 600 GeV. In addition, we also found that the total transverse energy of an event is useful for distinguishing between heavy-quark production and the top-quark background.
