This paper presents a search for standard model Higgs boson
production in association with a W boson using events recorded by the
CDF experiment in a data set corresponding to an integrated luminosity of
5.6 fb-1. The search is performed using a matrix element technique
in which the signal and background hypotheses are used to create a
powerful discriminator. The discriminant output distributions for signal
and background are fit to the observed events using a binned likelihood
approach to search for the Higgs boson signal. We find no evidence for
a Higgs boson, and 95% confidence level (C.L.) upper limits are set on
σ(pp̅ →WH)×B(H→bb̅ ). The observed limits range from 3.5 to 37.6
relative to the standard model expectation for Higgs boson masses between
mH=100 GeV/c2 and mH=150 GeV/c2. The 95% C.L. expected limit
is estimated from the median of an ensemble of simulated experiments and
varies between 2.9 and 32.7 relative to the production rate predicted
by the standard model over the Higgs boson mass range studied.
