... Abstract: We present a search for a low-mass Standard Model Higgs boson produced in association with a z boson decaying to charged leptons at a center-of-mass energy of s\sqrt{s}=1.96~TeV with the D0 detector at the Fermilab Tevatron collider. The search is performed in a large data set of events containing two opposite-sign leptons (electron, muon) and one or two b-tagged jets. 4:00pm, 472 Willamette Hall . ...
