| Abstract: | In this Letter, we present a precise measurement of the total ZZ production cross section in pp collisions at sqrts]=1.96 TeV, using data collected with the CDF II detector corresponding to an integrated luminosity of approximately 6 fb(-1). The result is obtained by combining separate measurements in the four-charged (???' ?') and two-charged-lepton and two-neutral-lepton (??νν) decay modes of the Z boson pair. The combined measured cross section for pp → ZZ is 1.64(-0.38)(+0.44) pb. This is the most precise measurement of the ZZ production cross section in 1.96 TeV pp collisions to date. |
