Search for the Standard Model Higgs Boson Decaying to a bb̅ Pair in Events with One Charged Lepton and Large Missing Transverse Energy Using the Full CDF Data Set

We present a search for the standard model Higgs boson produced in association with a W boson in √s=1.96 TeV pp̅ collision data collected with the CDF II detector at the Tevatron corresponding to an integrated luminosity of 9.45 fb-1. In events consistent with the decay of the Higgs boson to a bottom-quark pair and the W boson to an electron or muon and a neutrino, we set 95% credibility level upper limits on the WH production cross section times the H→bb̅ branching ratio as a function of Higgs boson mass. At a Higgs boson mass of 125 GeV/c2, we observe (expect) a limit of 4.9 (2.8) times the standard model value.
