Search for a Higgs Boson Produced in Association with a W Boson in pbar-p Collisions at sqrt{s} = 1.96 TeV

TL;DR

This paper reports a search for the Standard Model Higgs boson produced with a W boson in proton-antiproton collisions at 1.96 TeV, setting upper limits on production rates for masses between 100 and 150 GeV.

Contribution

It introduces a multivariate analysis technique to improve sensitivity in Higgs boson searches at the Tevatron collider.

Findings

Observed upper limit at 115 GeV is 5.6 times the Standard Model prediction.

Expected upper limit at 115 GeV is 4.8 times the Standard Model prediction.

Analysis covers Higgs masses from 100 to 150 GeV.

Abstract

We present a search for a standard model Higgs boson produced in association with a W boson using 2.7 1/fb of integrated luminosity of pbar-p collision data taken at sqrt{s} = 1.96 TeV. Limits on the Higgs boson production rate are obtained for masses between 100 GeV and 150 GeV. Through the use of multivariate techniques, the analysis achieves an observed (expected) 95% confidence level upper limit of 5.6 (4.8) times the theoretically expected production cross section for a standard model Higgs boson with a mass of 115 GeV.
