Search for Higgs boson production in dilepton and missing energy final states with 5.4 fb-1 of p-pbar collisions at sqrt(s) =1.96 TeV

TL;DR

This paper reports a search for the standard model Higgs boson in dilepton and missing energy final states using Tevatron data, setting upper limits on production rates at 165 GeV.

Contribution

First search for Higgs boson in dilepton plus missing energy channel at Tevatron with 5.4 fb-1 data, establishing new upper limits on production rate.

Findings

No significant excess observed above background.

Upper limits on Higgs production are 1.55 times the standard model prediction at 165 GeV.

Results constrain Higgs production cross section at Tevatron energies.

Abstract

A search for the standard model Higgs boson is presented using events with two charged leptons and large missing transverse energy selected from 5.4 fb-1 of integrated luminosity in p-pbar collisions at sqrt(s)=1.96 TeV collected with the D0 detector at the Fermilab Tevatron Collider. No significant excess of events above background predictions is found, and observed (expected) upper limits at 95% confidence level on the rate of Higgs boson production are derived that are a factor of 1.55 (1.36) above the predicted standard model cross section at Higgs boson mass of 165 GeV.
