Search for Neutral Higgs Boson Production in the Decay h to tau(mu) tau with the D0 Detector

TL;DR

This paper reports a search for neutral Higgs bosons decaying into tau pairs with one tau decaying into a muon, using D0 detector data, setting limits on model parameters without observing a significant excess.

Contribution

It presents the first search for Higgs to tau tau decays with a muon in the final state at the D0 detector, constraining MSSM parameters in the specified mass range.

Findings

No excess above background observed.

Excludes tan(beta) > 40-60 for certain MSSM scenarios.

Results set limits on Higgs production in the specified mass range.

Abstract

A search for the production of neutral Higgs bosons decaying into tau tau final states is presented. One of the two tau leptons is required to decay into a muon. The data were collected by the D0 detector and correspond to an integrated luminosity of about 1.0 fb-1. No excess is observed above the expected backgrounds. The results are interpreted in the Minimal Supersymmetric Standard Model. In the mass range 90<mA<200 GeV values of tan(beta) larger than 40-60 are excluded for the no-mixing and the mhmax benchmark scenarios.
