Measurement of the ZZ(*) production cross section in the four lepton channel at 8 TeV and 13 TeV and limits on anomalous triple gauge couplings with the ATLAS detector
Measurements of the cross sections of the production of pairs of electroweak gauge bosons at the LHC constitute stringent tests of the electroweak sector of the Standard Model and provide a model-independent means to search for new physics at the TeV scale.

description | Measurements of the cross sections of the production of pairs of electroweak gauge bosons at the LHC constitute stringent tests of the electroweak sector of the Standard Model and provide a model-independent means to search for new physics at the TeV scale. The ATLAS collaboration has measured inclusive and differential cross sections of the production of ZZ pairs in final states with four charged leptons using data corresponding to 20.3 /fb at a centre-of-mass energy of 8 TeV and data corresponding to 3.2 /fb at a center-of-mass energy of 13 TeV. The studies at 8 TeV are extended to the final state of two charged leptons and two neutrinos, which enhances the acceptance at high transverse momentum. These measurements are compared to calculations at NNLO in pQCD and provide constraints on new physics, by setting limits on anomalous triple gauge couplings. |
