TL;DR

This paper evaluates the potential for discovering neutral Higgs bosons in minimal supersymmetry at colliders through a specific tau and bottom quark decay channel, considering realistic backgrounds and detection efficiencies.

Contribution

It introduces a detailed analysis of Higgs boson detection prospects via the $bg o b\phi^0 \to b\tau^+\tau^-$ channel within the minimal supersymmetric model, including background calculations and realistic cuts.

Findings

Promising detection prospects for $A^0$ and $H^0$ Higgs bosons up to 1 TeV mass.

Realistic background analysis enhances the reliability of detection predictions.

Potential for discovery at CERN LHC and Fermilab Tevatron.

Abstract

We investigate the prospects for the discovery at the CERN Large Hadron Collider or at the Fermilab Tevatron of neutral Higgs bosons through the channel where the Higgs are produced together with a single bottom quark and the Higgs decays into a pair of tau leptons, $bg \to b\phi^0 \to b\tau^+\tau^-, \phi^0 = h^0, H^0, A^0$. We work within the framework of the minimal supersymmetric model. The dominant physics background from the production of $b\tau^+\tau^-$, $j\tau^+\tau^-$ ($j = g, u, d, s, c$), $b\bar{b}W^+W^-$, $W+2j$ and $Wbj$ is calculated with realistic acceptance cuts and efficiencies. Promising results are found for the CP-odd pseudoscalar ($A^0$) and the heavier CP-even scalar ($H^0$) Higgs bosons with masses up to one TeV.
