High Mass Higgs Boson Searches at the Tevatron

TL;DR

This paper reports on combined results from CDF and D0 experiments at the Tevatron, using up to 6.7 fb^-1 of data, to search for high mass Standard Model Higgs bosons, excluding certain mass ranges with 95% confidence.

Contribution

It introduces new search channels and reanalyzes previous data to improve sensitivity in high mass Higgs boson searches at the Tevatron.

Findings

Excluded Higgs mass range 158-175 GeV/c2 at 95% C.L.

Analyzed up to 6.7 fb^-1 of data from Tevatron.

Added new decay channels to enhance search sensitivity.

Abstract

We present results from CDF and D0 on direct searches for high mass standard model (SM) Higgs boson (H) in ppbar collisions at the Fermilab Tevatron at \sqrt(s) = 1.96 TeV. Compared to previous Higgs boson Tevatron combinations, more data and new channels (H -> W+W- -> lnujj, H -> WW -> l+tau + X and trilepton final states) have been added. Most previously used channels have been reanalyzed to gain sensitivity. Analyzing 5.9 fb^-1 of data at CDF, and 5.4-6.7 fb^-1 at D0, the combination excludes with 95% C.L. a standard model Higgs boson in the mass range of m_H = 158-175 GeV/c2.
