Search for Neutral Supersymmetric Higgs Bosons in $p\bar{p}$ Collisions at $\sqrt{s}=1.8$ TeV

TL;DR

This paper reports a search for neutral supersymmetric Higgs bosons in proton-antiproton collisions, finding no evidence and setting lower mass limits within the MSSM framework for high tan(beta) values.

Contribution

First search for neutral supersymmetric Higgs bosons in multi-b final states at Tevatron energies, establishing new mass limits in the MSSM parameter space.

Findings

No evidence of neutral Higgs bosons in the analyzed data.

Set 95% confidence level lower mass limits for Higgs bosons with high tan(beta).

Constraints on MSSM parameters based on the null results.

Abstract

We present the results of a search for neutral Higgs bosons produced in association with $b$ quarks in $p\bar{p}\to b\bar{b} \phi\to b\bar{b}b\bar{b}$ final states with $91 \pm 7$ pb$^{-1}$ of $p\bar{p}$ collisions at $\sqrt{s}=1.8$ TeV recorded by the Collider Detector at Fermilab. We find no evidence of such a signal and the data is interpreted in the context of the neutral Higgs sector of the Minimal Supersymmetric extension of the Standard Model. With basic parameter choices for the supersymmetric scale and the stop quark mixing, we derive 95% C.L. lower mass limits for neutral Higgs bosons for $\tb$ values in excess of 35.
