Abstract
We present a search for Wbb¯ production in pp¯ collisions at √s=1.96 TeV in events containing one electron, an imbalance in transverse momentum, and two b-tagged jets. Using 174 pb-1 of integrated luminosity accumulated by the D∅ experiment at the Fermilab Tevatron collider, and the standard-model description of such events, we set a 95% C.L. upper limit on Wbb¯ production of 6.6 pb for b quarks with transverse momenta pTb>20 GeV and bb¯ separation in pseudorapidity-azimuth space ΔRbb>0.75. Restricting the search to optimized bb¯ mass intervals provides upper limits on WH production of 9.0-12.2 pb for Higgs-boson masses of 105-135 GeV.
