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 7 TeV with 4.6 fb^-1 of data collected in 2011.  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 cross section values reported in the tables should be multiplied by a factor of 1.0141 to take into account the updated value of the integrated luminosity for the ATLAS 2011 data taking period.  The uncertainty on the global normalisation (\"Lumi\") remains at 1.8%.  See Eur.Phys.J. C73 (2013) 2518 for more details.\n\nThe 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 > 20 (25) GeV for muons (electrons))\n- |etaLepton| < 3.16\n- At least one lepton pair is required to have invariant mass between 66 and 116 GeV. If the second pair also satisfies this, the event is ZZ, otherwise if the second pair satisfies mll > 20 GeV it is ZZ*.\n- min(DeltaR(l,l)) > 0.2.\n\nThe 2l2nu channel fiducial region is defined as:\n- 2e+MET or 2mu+MET\n- ptLepton > 20 GeV\n- |etaLepton| < 2.5\n- mll must be between 76 and 106 GeV\n- -MET*cos(phi_METZ)>75 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 lepton for which ptLepton > 10 GeV\n- min(DeltaR(l,l)) > 0.3.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.62535.v1/t1","@type":"Dataset","description":"The measured fiducial cross sections.
