Search for neutral supersymmetric Higgs bosons in multijet events at sqrt(s)=1.96 TeV

TL;DR

This study searched for neutral supersymmetric Higgs bosons produced with bottom quarks in proton-antiproton collisions at 1.96 TeV, using data from the D0 detector, and set upper limits on their production within 90-150 GeV.

Contribution

First search for neutral supersymmetric Higgs bosons in multijet events at the Tevatron, providing constraints on their production cross sections in the specified mass range.

Findings

Results are consistent with the Standard Model expectations.

Upper limits are set on Higgs boson production cross sections.

No evidence for supersymmetric Higgs bosons was observed.

Abstract

We have performed a search for neutral Higgs bosons produced in association with bottom quarks in $p\bar{p}$ collisions, using 260 $pb^{-1}$ of data collected with the D0 detector in Run II of the Fermilab Tevatron Collider. The cross sections for these processes are enhanced in many extensions of the standard model (SM), such as in its minimal supersymmetric extension at large tan$\beta$. The results of our analysis agree with expectations from the SM, and we use our measurements to set upper limits on the production of neutral Higgs bosons in the mass range of 90 to 150 GeV.
