Abstract
The event rate for production of a Higgs boson of mass \ensuremath{\sim}1 TeV with decay $H\ensuremath{\rightarrow}\mathrm{ZZ}\ensuremath{\rightarrow}4$ charged leptons is of order 25 events per year at standard Superconducting Super Collider luminosity and the QCD background is of comparable size. By tagging a single forward jet of energy ${E}_{j}g1$ TeV and rapidity $2l|{\ensuremath{\eta}}_{j}|l5$ from the $\mathrm{qq}\ensuremath{\rightarrow}\mathrm{qqZZ}$ process, the QCD background can be essentially eliminated, with about 10 Higgs-boson signal events per year remaining, which amounts to 70% of the $\mathrm{qq}\ensuremath{\rightarrow}\mathrm{qqZZ}$ signal rate. The experimental separation of the vector-boson scattering subprocess is thereby possible.
