Search for Higgs Bosons Produced in Association with a Vector Boson in pp̅ Collisions at √s = 1.8 TeV

We search for Higgs bosons produced in association with a massive vector boson in 91{plus_minus}7 pb{sup {minus}1} of p{ovr p} collisions at {radical} (s) =1.8 TeV recorded by the Collider Detector at Fermilab. We assume the Higgs scalar H{sup 0} decays to a b{ovr b} pair with branching ratio {beta} , and we consider the hadronic decays of the vector boson V (W or Z ). Observations are consistent with background expectations. We place 95{percent} confidence level upper limits on {sigma}(p{ovr p}{r_arrow} H{sup 0}V){beta} as a function of the scalar mass (M{sub H{sup 0}}) over the range 70{lt}M{sub H{sup 0}}{lt}140 GeV /c{sup 2} . When combined with an analysis of the case where V is a leptonically decaying W , these limits vary from 23thinspthinsppb at M{sub H{sup 0}}=70 GeV/c{sup 2} to 17thinspthinsppb at M{sub H{sup 0}}=140 GeV/c{sup 2} . {copyright} {ital 1998} {ital The American Physical Society
