Search for neutral Higgs bosons in the multi-b-jet topology in 5.2fb-1 of ppbar collisions at sqrt(s)=1.96 TeV

TL;DR

This paper reports a search for neutral Higgs bosons in multi-b-jet events at the Fermilab Tevatron, setting new limits on their production in the context of the minimal supersymmetric standard model.

Contribution

It presents the first search in the three-b-quark channel at the Tevatron with 5.2fb-1 of data, extending exclusion limits for Higgs bosons in the MSSM.

Findings

No significant excess observed above background.

Limits set on Higgs production cross section times branching ratio.

Extended the excluded parameter space for MSSM Higgs bosons.

Abstract

Data recorded by the D0 experiment at the Fermilab Tevatron Collider are analyzed to search for neutral Higgs bosons produced in association with b quarks. The search is performed in the three-b-quark channel using multijet-triggered events corresponding to an integrated luminosity of 5.2fb-1. In the absence of any significant excess above background, limits are set on the cross section multiplied by the branching ratio in the Higgs boson mass range 90 to 300 GeV, extending the excluded regions in the parameter space of the minimal supersymmetric standard model.
