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

Abstract

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