Searches for the Higgs boson at the Tevatron

TL;DR

This paper reports on the search for the Standard Model Higgs boson at the Tevatron collider, combining multiple channels and observing a modest excess of events around 125 GeV, consistent with Higgs production.

Contribution

It presents the most comprehensive Tevatron search results for the Higgs boson in the 100-200 GeV range, including analysis improvements and combined channel results.

Findings

Observed a 3.0 sigma local excess at around 125 GeV

Global significance of the excess is approximately 2.5 sigma

Results are consistent with Higgs boson production in the Standard Model

Abstract

We present the results from the Tevatron on the direct searches for Standard Model Higgs boson produced in $p\bar{p}$ collisions at a center of mass energy of 1.96 TeV, using the data corresponding to the integrated luminosity of 10fb$^{-1}$. The searches are performed in the Higgs boson mass range from 100 to 200 GeV/c$^{2}$. The dominant production channels, $H\rightarrow b\bar{b}$ and $H \rightarrow WW$, are combined with all the secondary channels and significant analysis improvements have been implemented to maximize the search sensitivity. We observe a significant excess of data events compared to background predictions with the local significance of 3.0 standard deviations. The global significance for such an excess anywhere in the full mass range investigated is approximately 2.5 standard deviations.
