Measurement of ZZ production in leptonic final states at s of 1.96 TeV at CDF
Abstract
In this paper we present a precise measurement of the total ZZ production cross section in pp 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 (llvv) decay modes of the Z. The combined measured cross section for pp ZZ is 1.64(+0.44)(-0.38) pb. This is the most precise measurement of the ZZ production cross section in 1.96 TeV pp collisions to date.
