Search for Higgs bosons decaying to tau pairs in ppbar collisions with the D0 detector
D0 Collaboration, V. Abazov
TL;DR
The analysis seeks upper limits on Higgs-boson production cross section times branching ratio across Higgs masses. It uses selected lepton–tau channels and visible-mass spectra in a likelihood calculation; its MSSM interpretation reaches sensitivity around tan β = 50 below MA = 180 GeV and sets the most stringent hadron-collider limits.
Problem
The analysis seeks upper limits on Higgs-boson production cross section times branching ratio as a function of Higgs-boson mass.

Selected eτh, µτh, and eµ events are analyzed using the full visible-mass spectra in a likelihood-ratio limit calculation.

The MSSM interpretation reaches sensitivity around tan β = 50 for MA below 180 GeV and sets the most stringent neutral MSSM Higgs production limit at hadron colliders.
Source: p. 6Takeaways & Limitations
The reported exclusion applies to the mmax h and no-mixing scenarios under the stated CP-conserving MSSM assumptions.
Source: p. 6The SM-width limits assume a width negligible relative to Mvis resolution, and the MSSM interpretation considers two CP-conserving scenarios.

Abstract
from arXiv · showhide
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.
