dc.description.abstract
We report on a search for anomalous production of Z boson pairs through a massive resonance decay in
data corresponding to 2:5:9 fb1 of integrated luminosity in pp collisions at
ffiffiffis
p
1:96 TeV using the
CDF II detector at the Fermilab Tevatron. This analysis, with more data and channels where the Z bosons
decay to muons or jets, supersedes the 1:1 fb1 four-electron channel result previously published by CDF.
In order to maintain high efficiency for muons, we use a new forward tracking algorithm and muon
identification requirements optimized for these high signal-to-background channels. Predicting the
dominant backgrounds in each channel entirely from sideband data samples, we observe four-body
invariant mass spectra above 300 GeV=c2 that are consistent with background. We set limits using the
acceptance for a massive graviton resonance that are 70 times stronger than the previously published
direct limits on resonant ZZ diboson production.
