WWsignatures from top quarks at the Fermilab Tevatron

If $W^{+}$ $W^{\mathrm{-}}$ production at the Fermilab Tevatron exceeds the electroweak rate, the most economical explanation will be QCD production of a heavy top quark pp¯→tt¯X with t→${\mathrm{bW}}^{+}$, t¯→b¯$W^{\mathrm{-}}$ decays. The cleanest signatures are found in events containing two isolated high-$p_T$ charged leptons (e, μ, or τ) with missing $p_T$. We suggest ways to confirm such signatures and to extract the top-quark mass.
