Abstract

We present a search for the standard model Higgs boson in final states with a charged lepton (electron or muon), missing transverse energy, and two or three jets, at least one of which is identified as a $b$-quark jet. The search is primarily sensitive to $WH→ℓνb\bar b$ production and uses data corresponding to $9.7  \text{fb}^{−1}$ of integrated luminosity collected with the D0 detector at the Fermilab Tevatron $p\bar p$ Collider at $\sqrt s=1.96  \text{TeV}$. We observe agreement between the data and the expected background. For a Higgs boson mass of 125 GeV, we set a 95% C.L. upper limit on the production of a standard model Higgs boson of $5.2×σ_{\text{SM}}$, where $σ_{\text{SM}}$ is the standard model Higgs boson production cross section, while the expected limit is $4.7×σ_{\text{SM}}$.
