Searches for a high mass Standard Model Higgs boson at the Tevatron

TL;DR

This paper reports on searches for a high mass Standard Model Higgs boson at the Tevatron, setting limits and excluding certain mass ranges based on data from the CDF and D0 experiments.

Contribution

It presents the most sensitive search results for a high mass Higgs boson at the Tevatron, including the first exclusion of the 160-170 GeV mass range.

Findings

No significant excess observed over background.

95% CL limits set for Higgs masses 100-200 GeV.

Excludes SM Higgs in 160-170 GeV range.

Abstract

Higgs boson searches are commonly considered one of the main objectives of particle physics nowadays. The latest results obtained by the CDF and D0 collaborations are presented here when searching for Higgs boson decaying into a W-boson pair, currently the most sensitive channel for masses greater than 130 GeV. The presented results are based on an integrated luminosity that ranges from 3.0 to 4.2 fb^-1. No significant excess over expected background is observed and the 95% CL limits are set for a Standard Model (SM) Higgs boson for different mass hypotheses ranging from 100 GeV to 200 GeV. The combination of CDF and D0 results is also presented, which exclude for the first time a SM Higgs boson in the 160 < mH < 170 GeV mass range.
