Search for neutral MSSM Higgs bosons decaying to tau pairs in p-pbar collisions at sqrt(s)=1.96 TeV

TL;DR

This paper reports a search for neutral MSSM Higgs bosons decaying into tau pairs in proton-antiproton collisions at 1.96 TeV, using data from the CDF II detector, and sets exclusion limits on their production.

Contribution

First search for MSSM Higgs bosons decaying to tau pairs at Tevatron energies with new exclusion limits.

Findings

No significant excess observed above background.

Set exclusion limits on Higgs production cross section.

Mass range 90-250 GeV/c^2 constrained.

Abstract

We present a search for neutral supersymmetric Higgs bosons decaying to tau pairs produced in p-pbar collisions at sqrt(s) = 1.96 TeV. The data, corresponding to 310 pb^(-1) integrated luminosity, were collected with the CDF II detector at the Tevatron collider at Fermilab. No significant excess above the standard model backgrounds is observed. We set exclusion limits on the production cross section times branching fraction to tau pairs for Higgs masses in the range from 90 to 250 GeV/c^2.
