Abstract
We study the extraction of the heavy-Higgs-boson signal H → W + W - → ℓ ¯ ν , ℓ ν ¯ ( ℓ = e or μ ) from the standard-model background at hadron supercolliders. By tagging a single forward jet with energy E j > 3 TeV and pseudorapidity 3 < | η j | < 5 and by vetoing central jets of transverse momenta p Tj > 60 GeV in the pseudorapidity range 0 < | η j | < 3 , the QCD WWj and t t ¯ j → WWb b ¯ j backgrounds are suppressed. For m H = 1 TeV there are about 46 signal events from electroweak-vector-boson scattering (of which 36 events are of Higgs-boson origin) at the Superconducting Super Collider (SSC) for an integrated luminosity of 10 fb - 1 and 10 other events from the WWj and t t ¯ j backgrounds for m t = 140 GeV. The experimental separation of the vector-boson-scattering subprocess is thereby possible. At the CERN Large Hadron Collider, with an E j > 2 TeV jet energy cut, all cross sections are about a factor of 10 below the SSC values.
