Search for the standard model Higgs boson decaying to a bb¯ pair in events with one charged lepton and large missing transverse energy using the full CDF data set

Abstract

We present a search for the standard model Higgs boson produced in association with a W boson in ?s=1.96??TeV p¯p 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?b¯b 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.
