We search for the Higgs boson produced
in association with a Z or W boson. We consider a scenario where Z
decays to a pair of neutrinos, or W decays to a charged lepton and
neutrino and the electron or muon escape detection; the Higgs boson
a b-bbar pair. The data were collected with the CDF II detector at the
Tevatron collider at Fermilab, and correspond to an integrated
luminosity of 2.1fb-1. The acceptance has been drastically increased
with respect to the previous analysis by releasing the cuts on jet ET's
and number of jets, and implementing a NN to remove the huge
backgrounds that enter as a consequence of the loosening of these cuts.
As a result this analysis is sensitive to WH->taunubb decays. An
additional NN is used to discriminate the Higgs signal from the
remaining backgrounds. We observe no significant excess over predicted
backgrounds in CDF data,
so we set an expected upper limit on the Standard Model cross section
times the branching ratio of 6.3 assuming MH=115GeV, and an observed
limit of 7.9
Public note for Summer '08 conferences.
The results should be considered preliminary until published in a refereed journal. They can be used in conference presentations with proper reference to the CDF Collaboration.
Please notify us if you want to include these results in your presentation.
