Search for Higgs bosons decaying into b anti-b and produced in association with a vector boson in p anti-p collisions at 1.8-TeV
The authors present a new search for H{sup 0}V production, where H{sup 0} is a scalar Higgs boson decaying into b{bar b} with branching ratio {beta}, and V is a Z{sup 0} boson decaying into e{sup +}e{sup -}, {mu}{sup +}{mu}{sup -}, or {nu}{bar {nu}}. This search is then combined with previous searches for H{sup 0}V where V is a W{sup {+-}} boson or a hadronically decaying Z{sup 0}. The data sample consists of 106 {+-} 4 pb{sup -1} or p{bar p} collisions at {radical}s = 1.8 TeV accumulated by the Collider Detector at Fermilab. Observing no evidence of a signal, they set 95% Bayesian credibility level upper limits on {sigma}(p{bar p} {yields} H{sup 0}V) x {beta}. For H{sup 0} masses of 90, 110 and 130 GeV/c{sup 2}, the limits are 7.8, 7.2, and 6.6 pb respectively.
