Resumo

We report a search for the standard model Higgs boson in the missing energy and acoplanar b-jet topology, using an integrated luminosity of 0.93fb-1 recorded by the D0 detector at the Fermilab Tevatron pp̄ Collider. The analysis includes signal contributions from pp̄→ZH→νν̄ bb̄, as well as from WH production in which the charged lepton from the W boson decay is undetected. Neural networks are used to separate signal from background. In the absence of a signal, we set limits on σ(pp̄→ VH)×B(H→bb̄) at the 95% C.L. of 2.6-2.3 pb, for Higgs boson masses in the range 105-135 GeV, where V=W, Z. The corresponding expected limits range from 2.8 to 2.0 pb. © 2008 The American Physical Society.
