摘要：

At the Superconducting Super Collider, W-boson pairs coming from ttbbW+W- provide a serious background to the detection of the Higgs boson through the decay HW+W-l+2 jets, a mode crucial to the study of longitudinal 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. © 1990 The American Physical Society.
