Higgs boson searches at the Tevatron

TL;DR

This paper combines results from the CDF and D0 experiments at the Tevatron to search for the Higgs boson in various production and decay channels, setting new exclusion limits and discussing future prospects.

Contribution

It provides the first combined analysis of multiple Higgs search channels at the Tevatron, improving exclusion limits and exploring a wide mass range.

Findings

Excluded SM Higgs masses between 158 and 175 GeV/c^2

Set 95% CL upper limits on Higgs production

Presented future sensitivity projections

Abstract

We present combined CDF and D0 searches for the Standard Model (SM) and Minimal Supersymmetric Standard Model (MSSM) Higgs boson using up to 6.7 fb$^{-1}$ of integrated luminosity from 1.96 TeV proton-antiproton collisions at the Tevatron. Specialized searches for Higgs bosons produced via gluon fusion, associated boson production, and vector boson fusion, decaying to $b\bar{b}$, $W^{+}W^{-}$, $\tau^{+}\tau^{-}$, and $\gamma\gamma$ are combined to produce 95\% CL upper limits on SM Higgs production as a function of mass. Current Tevatron limits are shown, including a new exclusion for SM Higgs masses between 158 and 175 GeV$/c^2$. We also present prospects for future sensitivity.
