Relevant to {ital WW} physics and heavy-Higgs-boson detection through its decay {ital H}{r arrow}{ital W}{sup +}{ital W}{sup {minus}}{r arrow}{ital l}{nu}+2 jets at the Superconducting Super Collider is the subprocess {ital bg}{r arrow}{ital Wt}. We study this process over the invariant-mass region {ital M}{sub {ital W}{ital t}}{gt}850 with respect to a 1-TeV Higgs boson using top-quark masses of {ital m}{sub {ital t}}=100 and 175 GeV. The cross sections in this region give a signal-to-background ratio of about 1:20. After applying further restrictions at the hadronic level for eliminating top quarks in conjunction with some basic parton level cuts, we find this ratio can be improved to 1:1. Polarization properties are also discussed.
