Search for $WH$ associated production in 5.3 fb$$^{-1}$$ of $$p\bar{p}$$ collisions at the Fermilab Tevatron
We present a search for associated production of Higgs and W bosons in p{bar p} collisions at a center of mass energy of {radical}s = 1.96 TeV in 5.3 fb{sup -1} of integrated luminosity recorded by the D0 experiment. Multivariate analysis techniques are applied to events containing one lepton, an imbalance in transverse energy, and one or two b-tagged jets to discriminate a potential WH signal from standard model backgrounds. We observe good agreement between data and background, and set an upper limit of 4.5 (at 95% confidence level and for m{sub H} = 115 GeV) on the ratio of the WH cross section multiplied by the branching fraction of H {yields} b{bar b} to its standard model prediction. A limit of 4.8 is expected from simulation.
