Measurement of the Z Z production cross section in p p collisions at s = 8 TeV using the Z Z → ℓ − ℓ + ℓ ′ − ℓ ′ + and Z Z → ℓ − ℓ + ν ν ¯ channels with the ATLAS detector

CERN-LHC. Measurements of the cross section for ZZ production using the 4l and 2l2nu decay channels in proton-proton collisions at a centre-of-mass energy of 8 TeV with 20.3 fb^-1 of data collected in 2012. The final states used are 4 electrons, 4 muons, 2 electrons and 2 muons, 2 electrons and missing transverse momentum, and 2 muons and missing transverse momentum (MET).

Measurement of the angular coefficients in Z -boson events using electron and muon pairs from data taken at s = 8 TeV with the ATLAS detector

CERN-LHC. Measurement of the angular coefficients of the Z-boson in the Collins-Soper rest frame using dielectron and dimuon pairs in proton-proton collisions at a centre-of-mass energy of 8 TeV with 20.3 fb^-1 of data collected in 2012. The measurement is performed in a narrow window of the Z-mass pole between 80-100 GeV, in fine bins of Z-boson momenta, and both integrated in rapidity as well as in coarse rapidity bins. The measurements are performed in the full phase space of the lepton kinematics, where the leptons are defined at Born-level.
