Extending the Higgs Boson Reach at the Upgraded Fermilab Tevatron

Abstract

We study the observability for a Standard Model-like Higgs boson at an upgraded Tevatron via the modes $p\bar{p}\to gg\to h\to \text{ww}\to \text{ljj}$ and $\ll$. We find that with c. m. energy of 2 TeV and an integrated luminosity of 30 fb${}^{-1}$ the signal may be observable for the mass range of $135\text{gev}\text{lsim}\text{mh}\text{lsim}180$ GeV at a $3-5\sigma$ statistical level. We conclude that the upgraded Tevatron may have the potential to detect a SM-like Higgs boson in the mass range from the LEP2 reach to 180 GeV.
