The jet-jet profile methods that we developed to enhance the heavy Higgs boson [r arrow][ital ZZ] signal over its backgrounds at a proton-proton collider energy of 40 TeV are extended to the heavy Higgs boson [r arrow][ital WW] signal and backgrounds. The dominant background is now the pair production of top quarks via the subprocess [ital gg][r arrow][ital t[bar t]]. The process [ital qg][r arrow][ital Wq] also contributes significantly, and backgrounds from the production of top quarks via the subprocess [ital bg][r arrow][ital Wt] and [ital WW] continuum are also included in the analysis but are less important. To enhance the signal, a profile analysis is performed on [ital both] the toward side'' (the [ital W][r arrow][ital l][nu] trigger side) and on the away side'' (the [ital W][r arrow] jet-jet system). We define observables that help distinguish between the transverse energy distribution of the signal and of the backgrounds in an electromagnetic and/or hadronic calorimeter system. By making cuts on [ital both] the toward- and away-side observables, signal to background enhancement factors around 1000 can be obtained.
