gg-->H-->tau tau at the Upgraded Fermilab Tevatron

We study the neutral Higgs boson production via the gluon fusion process with the $\tautau$ final state at the upgraded Fermilab Tevatron, including a complete simulation of signal channels and leading background processes. For the SM Higgs boson, this $h\to \tautau$ channel may provide important addition for the Higgs boson discovery in the mass range 120-140 GeV. In minimal supersymmetric models, natural enhancement for the signal rate over the SM expectation makes the $h,H,A\to \tautau$ signal observable for large $\tanβ$ and low $M_A$, which may lead to full coverage for SUSY Higgs parameters at the Tevatron with a moderate integrated luminosity.
