Contribution

First search for Higgs to tau pairs at Tevatron, providing the most stringent limits to date on their production cross section.

Findings

Set upper limits on Higgs production cross section times branching ratio.

Interpreted results within the minimal supersymmetric standard model.

Achieved the most restrictive limits at hadron colliders to date.

Abstract

We present a search for the production of neutral Higgs bosons phi decaying into tau+tau- final states in ppbar collisions at a center-of-mass energy of 1.96 TeV. The data, corresponding to an integrated luminosity of approximately 1 fb-1, were collected by the D0 experiment at the Fermilab Tevatron Collider. Limits on the production cross section times branching ratio are set. The results are interpreted in the minimal supersymmetric standard model yielding limits that are the most stringent to date at hadron colliders.
