At the Superconducting Supercollider {ital W}-boson pairs coming from {ital t{bar t}}{r arrow}{ital b{bar b}W}{sup +}{ital W}{sup {minus}} provide a serious background to the detection of the Higgs boson through the decay {ital H}{r arrow}{ital W}{sup +}{ital W}{sup {minus}}{r arrow}{ital l}{nu}+2 jets, a mode crucial to the study of longitudinal {ital W}'s in the TeV region. Considering a Higgs-boson mass of 1 TeV and a top-quark mass of 175 GeV we develop a set of cuts which yield a final signal-to-background ratio of approximately 3:1 and about 300 signal events. Most effective are the requirements of lepton isolation and high transverse momentum for the lepton and jets.
