Measurement of the ZZ production cross section using the full CDF II data set

We present a measurement of the ZZ-boson pair-production cross section in 1.96 TeV center-of-mass energy p¯p collisions. We reconstruct final states incorporating four charged leptons or two charged leptons and two neutrinos from the full data set collected by the Collider Detector experiment at the Fermilab Tevatron, corresponding to 9.7 fb-1 of integrated luminosity. Combining the results obtained from each final state, we measure a cross section of 1.04+0.32-0.25 pb, in good agreement with the standard model prediction at next-to-leading order in the strong-interaction coupling.We thank the Fermilab staff and the technical staffs of the participating institutions for their vital contributions.
