Search for the associated production of a b quark and a neutral supersymmetric Higgs boson which decays to tau pairs

TL;DR

This paper reports a search for a neutral supersymmetric Higgs boson produced with a b quark, decaying into tau pairs, using collider data, and sets constraints on the minimal supersymmetric model.

Contribution

First search for associated production of a neutral supersymmetric Higgs with a b quark decaying to tau pairs at Tevatron.

Findings

No significant excess over background observed.

Excluded a region of the MSSM parameter space.

Data consistent with background predictions.

Abstract

We report results from a search for production of a neutral Higgs boson in association with a $b$ quark. We search for Higgs decays to $\tau$ pairs with one $\tau$ subsequently decaying to a muon and the other to hadrons. The data correspond to 2.7fb$^{-1}$ of $\ppbar$ collisions recorded by the D0 detector at $\sqrt{s} = 1.96$TeV. The data are found to be consistent with background predictions. The result allows us to exclude a significant region of parameter space of the minimal supersymmetric model.
