Abstract
We report on a search for anomalous production of boson pairs through a massive resonance decay in data corresponding to of integrated luminosity in collisions at using the CDF II detector at the Fermilab Tevatron. This analysis, with more data and channels where the bosons decay to muons or jets, supersedes the 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 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 diboson production.
