We search for Higgs bosons produced in association with a massive vector boson in 91 +/- 7 pb(-1) of p(p)over-bar collisions at root s = 1.8 TeV recorded by the Collider Detector at Fermilab. We assume the Higgs scalar H(0) decays to a b(b)over-bar 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% confidence level upper limits on sigma(p(p)-over-bar --> H(0)V)beta as a function of the scalar mass (M(H0)) over the range 70 less-than M(H0) less-than 140 GeV/c(2). When combined with an analysis of the case where V is a leptonically decaying W, these limits vary from 23 ph at M(H0) = 70 GeV/c(2) to 17 pb at M(H0) = 140 GeV/c(2).

Abstract
We search for Higgs bosons produced in association with a massive vector boson in 91 +/- 7 pb(-1) of p(p)over-bar collisions at root s = 1.8 TeV recorded by the Collider Detector at Fermilab. We assume the Higgs scalar H(0) decays to a b(b)over-bar 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% confidence level upper limits on sigma(p(p)-over-bar --> H(0)V)beta as a function of the scalar mass (M(H0)) over the range 70 less-than M(H0) less-than 140 GeV/c(2). When combined with an analysis of the case where V is a leptonically decaying W, these limits vary from 23 ph at M(H0) = 70 GeV/c(2) to 17 pb at M(H0) = 140 GeV/c(2).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
