Search for the Standard Model Higgs Boson in the WH→ τ v b$$\bar{b}$$ Channel with the D0 Detector
- Univ. of Manchester (United Kingdom)
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 → τ 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.
