Book Synopsis Measurement of $ZZ$ Production in Leptonic Final States at $\surd{s}$ of 1.96 TeV at CDF. by :
Book excerpt: In this paper we present a precise measurement of the total ZZ production cross section in p{bar p} collisions at √s = 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 (lll′l′), and two-charged-lepton and two-neutral-lepton (ll??) decay modes of the Z. The combined measured cross section for p{bar p} → ZZ is 1.64{sub -0.38}{sup +0.44} pb. This is the most precise measurement of the ZZ production cross section in 1.96 TeV p{bar p} collisions to date.
