Search for the Higgs boson produced in association with Z -> l(+)l(-) using the matrix element method at CDF II
We present a search for associated production of the standard model 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 pp̄ collisions at the Fermilab Tevatron. We use event probabilities based on standard model matrix elements to construct...

| description | We present a search for associated production of the standard model 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 pp̄ collisions at the Fermilab Tevatron. We use event probabilities based on standard model 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 2.7fb-1 we see no evidence of a Higgs boson with a mass between 100GeV/c2 and 150GeV/c2. We set 95% confidence level upper limits on the cross section for ZH production as a function of the Higgs boson mass mH; the limit is 8.2 times the standard model prediction at mH=115GeV/c2. © 2009 The American Physical Society. |
