Search for Higgs boson production in oppositely charged dilepton and missing energy events in ${p\bar{p}}$ collisions at ${\sqrt{s} =}$1.96 TeV}

TL;DR

This paper reports a search for the Higgs boson in proton-antiproton collisions at 1.96 TeV, focusing on events with two leptons and missing energy, but finds no significant signal and sets upper cross section limits.

Contribution

First search for the Higgs boson in the $H ightarrow WW$ decay channel at the Tevatron with detailed event selection and background analysis.

Findings

No significant excess observed above background.

Upper limits set on Higgs production cross section.

Analysis based on 8.6 fb$^{-1}$ of data.

Abstract

We present a search for the standard model Higgs boson using events with two oppositely charged leptons and large missing transverse energy as expected in $H\rightarrow WW$ decays. The events are selected from data corresponding to 8.6 \ifb\ of integrated luminosity in $p \bar{p}$ collisions at $\sqrt{s}=1.96$ TeV collected with the D0 detector at the Fermilab Tevatron Collider. No significant excess above the standard model background expectation in the Higgs boson mass range this search is sensitive to is observed, and upper limits on the Higgs boson production cross section are derived.
