摘要
We study the extraction of the heavy-Higgs-boson signal HW+W-,(= e o r ) from the standard-model background at hadron supercolliders. By tagging a single forward jet with energy Ej>3 TeV and pseudorapidity 3<j<5 and by vetoing central jets of transverse momenta pTj>60 GeV in the pseudorapidity range 0<j<3, the QCD WWj and ttjWWbbj backgrounds are suppressed. For mH=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 ttj backgrounds for mt=140 GeV. The experimental separation of the vector-boson-scattering subprocess is thereby possible. At the CERN Large Hadron Collider, with an Ej>2 TeV jet energy cut, all cross sections are about a factor of 10 below the SSC values. © 1991 The American Physical Society.
