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).\n\nThe uncertainty on the global normalisation (\"Lumi\") is 1.9%.  See JHEP 01 (2017) 099 for more details.\n\n The 4l channel fiducial region is defined as:\n - 4e, 4mu or 2e2mu\n - Ambiguities in pairing are resolved by choosing the combination that results in the smaller value of the sum |mll - mZ| for the two pairs, where mll is the mass of the dilepton system.\n - ptLepton > 7 GeV (at least one with ptLepton > 24 GeV)\n - |etaMuon| <2.7, |etaElectron|<2.5 (for all but one electron), |etaElectron|<4.9 (for at most one electron)\n - Both lepton pairs are required to have invariant mass between 66 and 116 GeV.\n - min(DeltaR(l,l)) > 0.2.\n\n The 2l2nu channel fiducial region is defined as:\n - 2e+MET or 2mu+MET\n - ptLepton > 25 GeV\n - |etaLepton| < 2.5\n - mll must be between 76 and 106 GeV\n - -MET*cos(phi_METZ)>90 GeV, where phi_METZ is the angle between the Z and the MET\n - |MET - pTZ| / pTZ < 0.4, where pTZ is the transverse momentum of the dilepton system\n - No events with a jet for which ptJet > 25 GeV and |etaJet| < 4.5\n - No events with a third electron (muon) for which ptLepton > 7 (6) GeV\n - min(DeltaR(l,l)) > 0.3","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.76732.v1/t1","@type":"Dataset","description":"The measured fiducial cross sections and the combined total cross section compared to the SM predictions.
