Search for a Standard Model Higgs Boson with a Dilepton and Missing Energy Signature
- Princeton Univ., NJ (United States)
The subject of this thesis is the search for a standard model Higgs boson decaying to a pair of W bosons that in turn decay leptonically, H → W+W- → $$\bar{ℓ}$$vℓ$$\bar{v}$$. This search is performed considering events produced in p$$\bar{p}$$ collisions at √s = 1.96 TeV, where two oppositely charged lepton candidates (e+e-, e±μ±, or μ+μ}-), and missing transverse energy, have been reconstructed. The data were collected with the D0 detector at the Fermilab Tevatron collider, and are tested against the standard model predictions computed for a Higgs boson with mass in the range 115-200 GeV. No excess of events over background is observed, and limits on Standard Model Higgs boson production are determined. An interpretation of these limits within the hypothesis of a fourth-generation extension to the standard model is also given. The overall analysis scheme is the same for the three dilepton pairs being considered (e+e-, e±μ±, or μ+μ-); this thesis, however, describes in detail the study of the dimuon final state.
