摘要：

We compute the exact matrix elements for the tree level O(alpha-w4) process qq-->qqW+W- and the tree level O(alpha-s2-alpha-w2) mixed QCD-electroweak processes, gg-->qqBAR W+W-, etc. and use them to examine the Higgs boson signal in pp-->W+W-jj for the representative case m(H) = 800 GeV. By requiring two "tagging" jets, p(Tj) > 50 GeV and 2.5 < \eta-j\ < 5.0 (4.5) at the SSC (LHC), the W+W-jj backgrounds from the mixed QCD-electroweak process and the non-resonant purely electroweak qq-->qq W+W- process are significantly reduced. We find that the m(WW) distribution of the Higgs boson signal is poorly described by the s-channel Higgs pole approximation.
