Abstract

We present a search for the standard model Higgs boson using hadronically decaying tau leptons, in 1 fb^-1 of data collected with the D0 detector at the Fermilab Tevatron pp collider. We select two final states: τ^± plus missing transverse energy and b jets, and τ⁺τ^- plus jets. These final states are sensitive to a combination of associated W/Z boson plus Higgs boson, vector boson fusion, and gluon-gluon fusion production processes. The observed ratio of the combined limit on the Higgs production cross section at the 95% C.L. to the standard model expectation is 29 for a Higgs boson mass of 115 GeV.
