pp¯→tt¯H: A Discovery Mode for the Higgs Boson at the Fermilab Tevatron

The production of a standard model Higgs boson in association with a top quark pair at the upcoming high luminosity run ( $15{\mathrm{fb}}^{-1\mathrm{}}$ integrated luminosity) of the Fermilab Tevatron ( $\sqrt{s}=2.0\mathrm{TeV}$) is revisited. For Higgs masses below 140 GeV we demonstrate that the production cross section times branching ratio for $H\to b\overline{b}$ decays yields a significant number of events and that this mode is competitive with and complementary to the searches using $p\overline{p}\to WH,ZH$ associated production. For higher mass Higgs bosons the $H\to W^{+}{W}^{-}$ decays are more difficult but have the potential to provide a few spectacular events.
