Aad, G.; Abbott, B.; Adomeit, S.; Becker, S.; Biebel, O.; Bock, C. (2016): Measurement of the ZZ Production Cross Section in pp Collisions at root s=13 TeV with the ATLAS Detector. In: Physical Review Letters, Vol. 116, No. 10, 101801

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(-2.0)(+2.2) (stat)(-0.7)(+0.9) (syst)(-0.7)(+1.0) (lumi) pb. The results agree with standard model predictions.
