Abstract
We report on the results of a search for standard model Higgs bosons produced in association with bosons from collisions at . The search uses a data sample corresponding to approximately of integrated luminosity. Events consistent with the and signature are selected by triggering on a high- electron or muon candidate and tagging one or two of the jet candidates as having originated from quarks. A neural network filter rejects a fraction of tagged charm and light-flavor jets, increasing the -jet purity in the sample. We observe no excess production beyond the background expectation, and we set 95% confidence level upper limits on the production cross section times branching fraction ranging from 3.9 to 1.3 pb, for specific Higgs boson mass hypotheses in the range 110 to , respectively.
