Abstract

We present a search for Higgs bosons decaying into bb̅ and produced in association with W bosons in pp̅ collisions at √s = 1.96 TeV. This search uses 320 pb^-1 of the data set accumulated by the upgraded Collider Detector at Fermilab. Events are selected that have a high-transverse momentum electron or muon, missing transverse energy, and two jets, at least one of which is consistent with the hadronization of a b quark. Both the number of events and the dijet mass distribution are consistent with standard model background expectations, and we set 95% confidence level upper limits on the production cross section times branching ratio for the Higgs boson or any new particle with similar decay kinematics. These upper limits range from 10 pb for m_H = 110 GeV/c² to 3 pb for m_H = 150 GeV/c².
