We compute the exact matrix elements for the tree level O(α 4 W ) process qq→qqW + W − and the tree level O(α 2 s α 2 W ) mixed QCD-electroweak processes, gg → q q 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 <| η 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→qqW + 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.
