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

Abstract

We study the neutral Higgs boson production via the gluon fusion process with the $\text{tautau}$ final state at the upgraded Fermilab Tevatron, including a complete simulation of signal channels and leading background processes. For the SM Higgs boson, this $h\to \text{tautau}$ 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 $h,H,A\to \text{tautau}$ signal observable for large $\tan \beta$ and low $M_A$, which may lead to full coverage for SUSY Higgs parameters at the Tevatron with a moderate integrated luminosity.
