DOWNLOAD EBOOKThe authors report on the results of a search for standard model Higgs bosons produced in association with W bosons from p{bar p} collisions at √s = 1.96 TeV. The search uses a data sample corresponding to approximately 1 fb−1 of integrated luminosity. Events consistent with the W → l[nu] and H → b{bar b} signature are selected by triggering on a high-p{sub T} electron or muon candidate and tagging one or two of the jet candidates as having originated from b quarks. A neural network filter rejects a fraction of tagged charm and light flavor jets, increasing the b-jet purity in the sample and thereby reducing the background to Higgs boson production. They observe no excess l[nu]b{bar b} production beyond the background expectation, and they set 95% confidence level upper limits on the production cross section times branching fraction [sigma](p{bar p} → WH) · Br(H → b{bar b}) ranging from 3.9 to 1.3 pb, for specific Higgs boson mass hypotheses in the range 110 to 150 GeV/c2, respectively.
