Search for neutral Higgs bosons in multi-$b$-jet events in $p\bar{p}$ collisions at $\sqrt{s} = 1.96$ TeV

TL;DR

This paper reports a search for neutral Higgs bosons produced with b quarks at the Fermilab Tevatron, finding no significant excess and setting limits on MSSM parameters.

Contribution

First search for neutral Higgs bosons in multi-b-jet events at Tevatron, constraining MSSM parameter space.

Findings

No significant excess observed

Limits set on MSSM parameters

Analysis of 1 fb^{-1} of data

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. This production mode can be enhanced in the minimal supersymmetric standard model (MSSM). The search is performed in the three $b$ quark channel using multijet triggered events corresponding to an integrated luminosity of $1 \mathrm{fb}^{-1}$. No statistically significant excess of events with respect to the predicted background is observed and limits are set in the MSSM parameter space.
