Abstract: (arXiv)

We present a search for associated production of the standard model (SM) Higgs boson and a

Z

boson where the

Z

boson decays to two leptons and the Higgs decays to a pair of

b

quarks in

p\bar{p}

collisions at the Fermilab Tevatron. We use event probabilities based on SM matrix elements to construct a likelihood function of the Higgs content of the data sample. In a CDF data sample corresponding to an integrated luminosity of 2.7 fb

^{-1}

we see no evidence of a Higgs boson with a mass between 100 GeV

/c^2

and 150 GeV

/c^2

. We set 95% confidence level (C.L.) upper limits on the cross-section for

ZH

production as a function of the Higgs boson mass

m_H

/ the limit is 8.2 times the SM prediction at

m_H = 115

GeV

/c^2

.
