Search for neutral Higgs bosons decaying to tau pairs in association with b-quarks at the D0 Detector

TL;DR

This paper reports a search for neutral Higgs bosons decaying into tau pairs associated with b-quarks using data from the D0 detector, setting limits on production cross sections and excluding certain supersymmetric models.

Contribution

First search for neutral Higgs bosons decaying to tau pairs with b-quark association at the D0 detector, providing new exclusion limits in the 90-160 GeV/c^2 mass range.

Findings

Set cross section times branching ratio limits for Higgs production

Excluded certain supersymmetric scenarios at 95% CL

Analyzed data from 1.2/fb collected between 2006-2007

Abstract

We report results from a search for neutral Higgs bosons decaying to tau pairs produced in association with a b-quark in 1.2/fb of data taken from June 2006 to August 2007 with the D0 detector at Fermi National Accelerator Laboratory. The final state includes a muon, hadronically decaying tau and jet identified as coming from a $b$-quark. We set cross section times branching ratio limits on production of such neutral Higgs bosons in the mass range from 90 GeV/c^2 to 160 GeV/c^2. Exclusion limits are set at the 95% Confidence Level for several supersymmetric scenarios.
