Abstract

We search for Higgs bosons produced in association with a massive vector boson in 91 ± 7 pb^-1 of pp̅ collisions at √s =1.8 TeV recorded by the Collider Detector at Fermilab. We assume the Higgs scalar H⁰ decays to a bb̅ pair with branching ratio β, and we consider the hadronic decays of the vector boson V (W or Z). Observations are consistent with background expectations. We place 95% confidence level upper limits on σ (pp̅→H⁰V) β as a function of the scalar mass (MH⁰) over the range 70 < MH⁰ < 140 GeV/c². When combined with an analysis of the case where V is a leptonically decaying W, these limits vary from 23 pb at MH⁰ = 70 GeV/c² to 17 pb at MH⁰=140 GeV/c².
