We report a search for Standard Model (SM) Higgs boson production in association with a W± boson. This search uses data corresponding to an integrated luminosity of \math rm1.9 fb-1 collected with the CDF detector at Tevatron. We select events matching the W + jets signature and require at least one jets to be identified as b-quark jets . To further increase discrimination between signal and background, we use kinematic information in an artificial neural network. The number of tagged events and the resulting neural network output distributions are consistent with the Standard Model expectations, and we set an upper limit on the WH produ ction cross section times branching ratio σ(pp → W^±H)× BR(H→ bb) < 1.1 to 1.0 pb for Higgs masses from 110 GeV/c2 to 150 G eV/c2 at 95% confidence level.
