Search for MSSM Higgs Boson Production in Di-tau Final States with L=2.2 fb^-1 at the DO Detector

TL;DR

This paper reports a search for MSSM Higgs bosons decaying into tau pairs in proton-antiproton collisions at 1.96 TeV, using 2.2 fb^-1 of data, setting limits on the MSSM parameter space.

Contribution

First search for MSSM Higgs in tau final states at the Tevatron with new exclusion limits on mA and tan(beta).

Findings

No significant excess observed over background.

Excluded regions in MSSM parameter space.

Constraints improve previous bounds.

Abstract

A search for the production of neutral Higgs bosons decaying into tau anti-tau final states is presented in p-pbar collisions at a center-of-mass energy of 1.96 TeV. The integrated luminosity used for the study is about 2.2 fb^-1, collected by the DO Experiment at the Fermilab Tevatron Collider. No significant excess is observed over the background expectation. The results are interpreted in the Minimal Supersymmetric Standard Model (MSSM) and regions in the mA, tan(beta) parameter space for two MSSM benchmark scenarios are excluded.
