We present a measurement of the ZZ-boson pair-production cross section in 1.96 TeV center-of-mass energy pp¯ 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.

Abstract
We present a measurement of the ZZ-boson pair-production cross section in 1.96 TeV center-of-mass energy pp¯ 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.File in questo prodotto:
