Book excerpt: A search for the Standard Model Higgs boson is performed in 4.0 fb-1 of p$\bar{p}$ collisions at √s = 1.96 TeV, collected with the DØ detector at the Fermilab Tevatron. The final state considered is a pair of b-jets with large missing transverse energy and one hadronic tau decay as expected from the reaction p$\bar{p}$ → WH → [tau] v b$\bar{b}$. Boosted decision trees are used to discriminate the signal from the background. Good agreement is observed between data and expected backgrounds. For a Higgs boson mass of 115 GeV, a limit is set at 95% C.L. on the cross-section times branching fraction of (p$\bar{p}$→ (Z/W)H)×(H → b$\bar{b}$) which is 14 times larger than the Standard Model value.
