Abstract

The ZZ production cross section in proton-proton collisions at 13 TeV center-of-mass energy is measured using 3.2 fb−1 of data recorded with the ATLAS detector at the Large Hadron Collider. The considered Z boson candidates decay to an electron or muon pair of mass 66–116 GeV. The cross section is measured in a fiducial phase space reflecting the detector acceptance. It is also extrapolated to a total phase space for Z bosons in the same mass range and of all decay modes, giving 16.7 þ2.2 −2.0 ðstatÞ þ0.9 −0.7 ðsystÞ þ1.0 −0.7 ðlumiÞ pb. The results agree with standard model predictions.
