SUSY Higgs Searches at DZERO, Tevatron

TL;DR

This paper reports on the DZERO collaboration's searches for neutral MSSM Higgs bosons at the Tevatron, using proton-antiproton collision data, and sets constraints on the MSSM parameter space after no excess events were observed.

Contribution

First comprehensive searches for MSSM Higgs bosons at Tevatron Run II, combining multiple analyses to constrain the MSSM parameter space.

Findings

No excess events observed above background

Constraints placed on MSSM parameter space

Results improve previous limits on MSSM Higgs production

Abstract

During Run II of the Tevatron collider, D\O collaboration has made extensive searches for the neutral MSSM Higgs bosons ($\phi$), produced in $\rm p\bar{p}$ collisions at $\rm \sqrt{s}=1.96$ TeV. Two such analyses, addressing inclusive $\phi$ production with $\phi\to\tau^+\tau^-$, and associated $\phi b(\bar{b})$ production with $\phi\to b\bar{b}$ are reported here. No excess of events above the background expectation has been observed in any of these analyses. The results are combined to set constraints on the MSSM parameter space.
