Search for new heavy particles decaying to ZZ -> llll, lljj in p(p)over bar collisions at root s = 1.96 TeV

We report on a search for anomalous production of Z boson pairs through a massive resonance decay in data corresponding to 2: 5-2: 9 fb(-1) of integrated luminosity in p (p) over bar - collisions at root s = 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 fb(-1) 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/c(2) that are consistent with background. We set limits using the acceptance for a massive graviton resonance that are 7-20 times stronger than the previously published direct limits on resonant ZZ diboson production.
