Title: Exploiting h -> W^*W^* Decays at the Upgraded Fermilab Tevatron
Abstract: We study the observability of a Standard Model-like Higgs bosonat an upgraded Fermilab Tevatron via the mode $h \to \ww$. We perform detector level simulations forthe $gg\to h \to\ww\to \ll$ and$q\bar q'\to W^\pm h \to W^\pm \ww\to \ell^\pm\nu\ell^\pm\nu jj$ channels. We find that with a c.~m.~energy of 2 TeV and an integratedluminosity of 30 fb$^{-1}$ the signal should be observable at a 3$\sigma$ level or better for the mass range of $145\ {\gev} \lsim \mh \lsim 180$ GeV. For 95\% CL exclusion, the mass reach is$135\ {\gev} \lsim \mh \lsim 190$ GeV. We conclude that the upgraded Fermilab Tevatron will have the potential to significantly advance our knowledge of Higgs boson physics.
