We report on the results of a search for standard model Higgs bosons produced in association with W bosons from p (p) over bar collisions at root s = 1.96 TeV. The search uses a data sample corresponding to approximately 1 fb(-1) of integrated luminosity. Events consistent with the W -> lv and H -> b (b) over bar signature are selected by triggering on a high-p(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. We observe no excess lvb (b) over bar production beyond the background expectation, and we set 95% confidence level upper limits on the production cross section times branching fraction sigma(p (p) over bar -> WH)xBr(H -> b (b) over bar) ranging from 3.9 to 1.3 pb, for specific Higgs boson mass hypotheses in the range 110 to 150 GeV/c(2), respectively.
